    I just received one my Monoprice 15 watt amp so I thought I'd share my experience so far but I also have a few questions. Seems like a pretty awesome, no so little, amp so far. I was expecting this thing to be much heavier. It is louder than I expected, loud enough to cause hear damage for sure when cranked in my house. I bought the new 'improved' version, though I think I like the look of the old on better. This little sucker is mean too, lots of gain and growl, I can only imaging what you can make it sound like experimenting with tubes or modding it. The reverb tank seems much better than the old plastic one but it still seems to jangle at higher volumes. I have an old teal stripe Peavey Bandit with a Scorpion speaker in it. I was thinking about putting the Scorpion and the reverb tank from the Bandit in the Monoprice amp. Big question, does anyone know if its safe to run the Monoprice amp with the reverb tank removed entirely? I've got an Alesys Quadraverb in the FX loop so technically I don't need the mechanical reverb tank anyway. I'm thinking of getting a DOD Gunslinger and a boost or overdrive pedal to go in the front along with a wah pedal. Any thoughts or experience with that? This amp has enough gain and growl to it, it might not need a distortion pedal.

    I had some noise issues but i cleaned out the tube sockets a couple of times and now it's working great. I was doing some work on my Strat so i just go to try it today through the amp. It sounds great, even at low volume. I can't wait to crank it up. I'm in an apartment so I have to wait. I think my Hot Rod Deluxe is going up for sale.

    Regarding the new reverb tanks still having a microphonics issue, I'm going to buy a reverb tank bag and see if that helps.

    You can also get a pair of electrical safety gloves, leather over rubber, make sure they are EH rated. You can get EH rated foot ware as well that good for up to 1000 volts to keep you from becoming a good ground. Just remember if a part of you is touching metal other than your feet, you will become the path to ground at that contact point.

    Try out a Kemper and you will become a believer.

    What reverb tank can I replace the stock on in my version 2 with? I found some mod tanks but the impedences don't match exactly.

    Not doubting you a bit, but not for $1800-$2000. Not in my ballpark, & not even slightly interested in trying. I'll take your word for it.

    I have a gunslinger, I think it is a great pedal, love it. I am in the process of building a bunch of VFE pedals but the gunslinger will stay, plus I got it for $28 new shipped off Reverb. That being said one of the best things I've gotten for my guitar setup is a MXR Iso-brick, went from a lot of noise, some whistling etc with pedals active to nearly silent, way quieter then a tube amp should be. I would buy one again in a heartbeat. (both)

    How does this amp compare with a vox ac15c1?

    I’ve had both, I prefer the Monoprice the vox was way too bright.

    Same experience. Put a greenback or equivalent in the MP and you get a beautiful Vox-like chime that’s not as piercing. Even though both are EL84 powered and 15 Watts, the Vox was noticeably louder with more headroom (to my ears). Bigger cab, likely a beefier OT will contribute to that.

    First post here, as this seemed to be the place i got the most info on this amp. Got my 15w in, and have played it a little so far. A bit muddy with a 335-type guitar, but still very new. I'm going to resist the urge to upgrade anything until the 70/80 is broken in. Might swap out some tubes i have lying around, but that's about it for now. 4 kids can make it difficult to find time to break a new speaker in.
    Coming from a Peavey Classic 50 2x12, this will be quite a bit lighter to cart around, which i'm looking forward to. So thanks for all the detailed info, this was an awesome deal on a solid tube amp that won't break my back!

    I will mention to the guys talking about the Caline Orange Burst, i dig that pedal & recommend it for neutral, more modern gain tones (esp for the price). And if you're looking at the Mad Professor Sweet Honey, check out Joyo's Sweet Baby - it's similar in price to the Caline, and has become one of my go-to overdrives, even with an original Nobels ODR-1, an old Analogman TS9 Brown, and a Fulldrive2.

    V1 tube was cracked when I pulled it out - I don't think I cracked it, as I read others had damaged them upon pulling them out & was extra gentle, so it may have been already cracked and causing issues. Tried several tubes i had lying around (12AX7s and 12AU7s) and landed on an old GE 12AX7. Sounds way better already. Will still let the speaker break in before doing anything else.

    Definitely worth that $129.99, open box price. These amps are not great but at that price it's crazy not to check out as a spare; to keep in another room, rehearsal spot, loaner...whatever.

    I got mine on a couple stacked discounts a few months ago, $123 total and (I think) about $146 shipped.

    Pre-amp tube swaps make a huge difference.
