    Can anyone explain this portion of the Tore-Vibe circuit to me?

    The part I'm wondering about is the part I've drawn an orange box around: Following the bias tremolo triode stage, why is there this weird RC network before the final amplification stage? Is it trying to do some kind of high-pass filter that needs multiple capacitor stages to do? Or is it...

    Way Huge Saucy Box circuit?

    Can someone confirm 100% what kind of circuit it really is? What kind of diodes/clipping? I'm just curious. I don't think it's a reduced version of the Pork Loin because this one is fat and a bit muddy/dark. SB is the opposite. TGP swear that it is NOT a clone of the Klon but ... to my ears...

    S'plain this voltage divider please...

    I've been wringing out the Tiny Terror circuit for all it's worth and I'm almost done but I stumbled upon a schematic Mercury Magnetics included for their Holy Terror upgrade mods and I'm really curious about how the voltage divider affects the circuit or more to the point, what happens to the...

    Help me understand differences between 50 watt and 100 watt plexi

    Hey, just researching, wondering if those in the know could help me understand what the differences are, and how they affect each's sound. Here are some differences I noticed when looking at the schematics below: 1. It looks like the 100 watt has a 100uf cap between ground and the center tap...

    Fender Machete Gut Shots

    While I was working at Fender we released the High Gain 50-watt (U.S.A. Made) All-Tube Fender Machete. Two channels. Pristine cleans (w/ switchable boost -killer overdrive-) and one of the best high gain channels I have ever heard. Active EQ, Cab emulated and dry XLR out w/speaker mute. (The amp...

    Question about echoplex pedal marketing decisions

    Why is it that companies ended up releasing "echoplex preamp" pedals with circuits far more complicated than the actual echoplex preamp? This is the Xotic EP Booster schematic: By contrast, here's (approximately) the actual echoplex preamp schematic: One would think it'd be a lot simpler...

    Modified 2-Pickup Esquire Blend Circuit w/4-Way.....?

    I'll try and keep this simple. I'm building a Partscaster with a Lollar Charlie Christian neck pickup, Broadcaster-style bridge pickup. I want to use a 2-pickup, no tone knob, Esquire blend circuit, but with a 4-way switch. Here's my idea (open to suggestions on the following): 1. Bridge pickup...

    Using both sides of 12AX7 in parallel?

    Is it possible to use a 12ax7 like that? For example: Connection pin 2 and 7 seems obvious...the signal gets to the other side of the tube no problem...but what about the output of that tube (pin 1 and 6 in the case of most Fender circuits for V1)? The 5F1 basically has them in series: V1a >...

    Idea for series/parallel + coil tap wiring: feedback please?

    As someone relatively new to guitar pickups and their tonalities, I want a setup that lets me test humbuckers in series, parallel and split coil all in the same guitar. I couldn't find any exact wiring for what I had in mind, so I came up with this and thought I'd share (firstly to get feedback...
