    I'd use EHX Switchblade Plus for such a purpose...

    That one is also for switching amp inputs. I'm trying to switch amp outputs to one cabinet. It's hard to do with MV50 because there is voltage on both speaker leads. Tube amps with transformer driving speaker can be grounded on one lead, and they make pedals to do this, but won't work with MV50.

    OK, I came to this thread a few years too late, but what a great repository of information! Well, I've finally made my way through it as I'm considering buying a "Clean" or a "Boutique". I use pedals but also like some amp overdrive as well, so this choice would come down to a couple of factors. Are the cleans of the Boutique still Fender- Blackface or different and if so, how? And I'd have to hope that the Boutique would (at least at the lower levels of Gain) handle reverb and delay in front. In either case, I would be mostly using the amp though headphones and the opinions here seem ambivalent at best.

    But my real concern is that I was surprised to see quite a few issues of power cutting out, volume dropping, and that 16 ohm speaker cutout at high volume. Dos anyone know if these have become quite common problems or if Vox has responded by taking care of them?

    Hopefully some of you might chime in on some of my questions and concerns. Cheers!

    I can't comment on the Boutique as I don't own one. I have the Clean, and at one time I also had the AC (but ended up selling the AC). I use pedals to get my overdrive, and I also use modulation, delay and reverb all in front of my Clean (of course, since there is no loop). It works like any other clean amp. Since my overdrive comes from pedals, its a non-issue. In the past, I have used reverb into overdriven amps, and didn't particularly have a problem with it, but others say it "doesn't work". I guess it all depends on what you are looking for.

    I have never had power drop out, and I have never had volume drop off. I use either 4ohm or 8ohm speakers, partly because that is what I have, and partly because I want as much power as possible. In general, I wouldn't recommend running at 16ohms unless you simply have no choice.

    I really love my Clean. Ever since getting it, my Princeton clone has become my home amp (mostly). I take the Clean to the weekly blues jam, as well as band practice. I have used it at gigs too. With the right pedals, it does the job very well, and fits in a camera case that I then place in my backpack.

    Just do it!

    I've understood that the Clean is really clean? As in doesn't appreciate pushing the amp itself to overdrive.

    Actually, it sounds pretty decent when pushed. A touch muddy maybe, but I suspect that can be dialed out.

    Could the MV Clean work okay as a keyboard amp?

    To a point maybe. But as you turn it up, it does thicken a little which might not suit the keyboard so well.
    Keyboards work well into PA type amps. So another option in a similar price range would be a powered wedge monitor.

    Thanks for this information Steve, and sorry for my delay in responding. Anyway I went ahead and bought the Clean. I've had absolutely no problems with it at all.

    Some observations:

    I've compared it extensively with my 1998 Hot Rod Deville 410 (though the cab's speakers). I can get tones from both amps (Deville Clean of course) that are basically indistinguishable from one another. I wish I had a Princeton around, but I'm guessing that with the Treble around 2 o'clock and the bass around 10 o'clock it would come pretty close. Perhaps Steve or someone else might be able to comment on this!

    Cranked: Not so great, but backed off slightly and I find it a very usable base tone equally good with pedals in front.

    Attenuation: nothing bad to say. I'm very impressed.

    Lack of effects loop: I'm surprised that so many YT superstars nowadays always hit on lack of effects loop. I've always had one and never used it because I get perfectly good tones in front of the amp.

    My daughter preferred the MV50 in almost every comparison and suggested that I should sell the HRDv especially as she preferred the MV50 through a WGS ET65 speaker which i'm putting into a custom 1x12 cab!

    I initially bought it to use through headphones when necessary, but it's really not very good except with super clean tones in which case it is excellent.

    My only real "complaint" is that I want to use this on top of a speaker cab, not on the pedalboard, and of course, it is really challenging to avoid it falling off due to cable movement! Obviously, this isn't a real issue as it couldn't be otherwise given its ultra-lightweight design. I'm thinking about solutions to perhaps build into my speaker cab design, but perhaps other users have already thought up good, workable solutions? I've searched the web and surprisingly I haven't found anything!

    I'm really happy with this amp and can actually see myself selling off my larger equipment. Along with a 5e3 clone, it more than serves all of my foreseeable needs!

    A quick update on my Clean purchase. My earlier "complaint" had been about amp stability. I have it sitting on top of a BassBreaker 15 head and it's never moved even a tiny bit. I play through my pedal board and then into the amp, so I guess this reduces the chances of pulling it off the cab unless I yank the entire pedal board!

    Still love the amp. I also recently bought a Boutique, which I thought I'd use as wet/dry or even stereo, but I actually prefer to have the two amps on an AB switch so that I can run the Boutique with some really creamy overdrive, but if I back off my guitar volume, I can also get a richer (??) creamier (??) clean than from the Clean amp head. The Boutique is superb, but I guess I'd say that the Clean is just slightly better overall -- lower noise floor, more control of EQ, and with the right pedals I can get similar overdriven tones as I can with the Boutique. But I should say that certain pedals, such as the OCD, do sound that much tighter and perhaps better when driving the slightly overdriven Boutique, but not by a huge margin.

    One question for anyone who is still visiting this thread. I've tried to find responses via Google and internal search engines for different forums but have come up dry.

    Has anyone tried taking the Line Out signal into the Return of an effects loop of a good tube amp?

    I thought I'd try it as a possibility for a wet/dry alternative and just to see what it sounded like using real power tubes. I ran the Boutique into the Return of my HotRod Deville. Wow. I was blown away with the fullness of the tone. And I got the additional benefit of having the HotRod's reverb and presence after the Vox. Very nice. Now if I could figure out how to make the Vox switchable in and out of the Effects Loop, I could use either the HRDv's own preamp, or use a Vox as an alternative preamp! Of course, it means that I'd be lugging the HRDv around as needed! But hey, I could I imagine say a Clean (to give a truer BF tone), a Boutique, and even a Rock on some sort of switching system to go through the power tubes of the HRDv for additional warmth. What a rig!

    Late into this one too. I've had both a Boutique and a Rock. Liked the Boutique, hated the Rock.

    The Boutique: very nice cleans and turbo gain just at the end of the dial. Before that, very usable and organic OD. Versatility is the word for the Boutique.

    The Rock: No cleans to speak of from very low on the gain knob. More of a one trick pony.

    Why didn't I keep them ? The lack of an effet loop. Any effect I'd put up front, was tenfold with gain. I like a little reverb and delay, and with the MV50's, I never found the dialing sweet spot.

    I never thought of keeping the Boutique as a preamp ... damned.

    Hmm...we've gone most of the year without posts to this club thread. So let me break the silence: I've joined the MV50 ownership club!

    I've posted here before when I was just an interested TDPRI member GASing over one of these amps. I've actually been GASing over them since they first came out, like four years ago. I first had my sights set on the AC model, but when the came out with the Mini Super Beetle, I changed my focus. To me, the MSB is an MV50 AC with a better tone stack and built in 'verb and trem, as well as an accompanying 1x10" cabinet.

    At first, I didn't pull the trigger on any of the MV50s because I couldn't try one. When they were first debuted, I checked local stores. One didn't carry them, the other (the local GC affiliate) got exactly one when the first hit the market. I was told it sold the same day, and they never got any more of them. Another factor is I didn't (and still don't) have a cab to plug one into.

    As for not pulling the trigger on an MSB, I've found it hard to do so because it's so much like my VOX Pathfinder 15Rs, so it's hard to justify the expense. I've test driven one at the local GC 3-4 times now. If money were no object, I would have already bought one, no matter its tonal similarities to the Pathfinder 15R. But I'm an old retired guy that tries to make gear purchases strictly from money from gigs, so I'm slow to move on gear purchases, even though the MV50s were just $200 then $220, and the MSB $300/$330.

    But the recent sale price on the MV50s changed that. (The sale continues through the remainder of the month, BTW.) At $140, they became instantly more accessible, and after a gig at the start of the month (Sept. 4th) garnered me $206 in base pay plus tips, I decided this was a good time to buy a brand new under warranty MV50 for $80 less than the usual retail price.

    Instead of ordering online, I went to my go-to guitar store in town, Clawson's Music. They had the various models in stock, and for the September sale price of $140, so I bought one on the spot. So I immediately had "my head in hand," so to speak. (I even created a NAD thread with that line as its title, see here.)

    I bought the Boutique version, BTW, a couple of days after that gig, on the 6th of September, specifically. The day after that, I left on a weeklong camping trip, so I had limited time to put the Boutique through its paces. To date, I'm still getting familiar with it. It's slow going because of a lot of other things going on right now. But I've plugged five of my seven electric guitars into it thus far. More to come...

    Look forward to hearing your thoughts on this amp. I haven't been playing much during the last several months, but I was finding that overall I preferred the Clean to the Boutique, but I'm still hanging onto both of them for now!

    I haven't had the time that I'd like with it yet. Like I said, I bought it, and the next day took off on a week-long camping trip. Got back, and found news of my younger brother's failing health. He passed away on Thursday, so I haven't plugged into it in days. I'll get back to it, but for now, well, I'm sure you understand...

    Hi Hungry, i know this is a late reply to your message... but i am praying you're still around, and can shed a little more light on this.

    I have an MV50 rock model, and i feed that into an attenuator i built myself, which is housed in an aluminium box, on side of my cab. I also have my guitar hanging off the side of my cab.

    So, the other day, i had my mv50 powered up, grab my guitar off the holder, and one of the tuners touched my attenuator, and holey shiite batman, cab gave a solid "woof", and sparks zapped between attenuator and tuner.

    So i get my multimeter out, and i find 9 volts, between my gutar's metal hardware, and the attenuator casing. The attenuator casing is "grounded" to the ground wire of the speaker cable coming from the mv50, because standard speaker jacks are made that way. The negative side is assumed to be a ground, not a live negative. ie the negative side of the jack is always connected to where the jack mates with the chassis its screwed onto.

    I just tested with valve amp for comparison, and all was good, no voltage on the spkr cable -'ve side. So the spkr cable ground does seem properly grounded on my tube amp.

    So this sounds to me like it could be the result of what you were talking about when you said there was "voltage on both speaker leads", on the mv50? Are you saying the mv50 actually drives both sides of the speaker cable - whereas tube amps drive only one side (so the live side swings from +'ve to -'ve, but the other side stays at a nice ground??

    Where did you find this info!!!?

    I would like to ask Vox why this it not documented prominently in MV50 user manuals, at the very least?!!

    This is a potential timebomb, especially for people who insert any device like an attenuator (or amp/cab-switcher) between amp and speaker. It could have fried the electronics in my guitar quite easily.

    Similarly, if someone uses a speaker cable with metal plug (as most are) the plug cases are always in contact with the speaker ground wire as well, so those are live. Anything that is properly grounded, that touches speaker cable plug is going to get a good zap, and if it is more than an instantaneous little glancing touch, it will likely fry your mv50 and whatever else just came into contact with it.

    Likewise, if you run your speaker cable to a fancy $1500 ox box, you may fry that, or if the ox box doesn't mind a live ground, in itself, it may be ok - but you connect the line out on your ox box to your pc, and you may fry your pc.

    Has anyone actually thought through the consequences of having both sides of spkr cable being live??

    It sounds to me like there should be some really prominent warnings on this thing...

    And let me just add, that this horrifies me, because i love this little bastard... it really does sound great.

    Until i read your post, i thought it must be that the external plugpack power supply was just a piece of crap, and was letting the ground float, but now i think you have the real answer.

    On the tube amp side, i have a Mooer little monster AC, and a marshall dsl50, and i love them both, but i don't like to waste valve life on those when i'm just messing around, esp as the el84 valve life on the mooer is pretty low, the el84's don't last as long as many other valves, when they're driven hard.

    So with the MV50 rock model, i can keep the gain very low, and get some nice clean tones (also good for overdrive pedals) as long as volume is below 3 or 4, which is still good and loud into a 4x12 cab, in a bedroom :) Or i can ditch the overdrive pedals and crank up the gain and master vol, to get some absolutely excellent distortion from the amp itself, and then tame the volume with attenuator, which i prefer.

    Just found out that most solid state amps are "differential" amps, with both -'ve and +'ve being live, and valve amps are the oddballs, in that most are made with a nicely grounded -'ve.

    Bloody hell, WATCH OUT GUISE... if you have gear like attenuators between your solid state amp and cab, your attenuator chassis will be live, if it has any normal sort of 1/4" headphone jack - in which the body of the jack is mounted directly to the chassis, because the body of the jack is also connected to the -'ve jack terminal...
