I suppose it's about time I figure some of this stuff out. I'll be glad once I'm a little more familiar with it, but it's tough to start.

Thanks for the help!

Wow, makes me almost wish this forum had feedback. But not really. You're the man! This came just as I'm getting into DIY amps, so... I'm really quite lucky!

Yeah, this is a great thread, Brad...thanks a lot!

I'm getting a decommissioned Marshall in October. It's unclear what's wrong with it, and as it's one with a PCB (a JTM 610) it may not be an easy fix. I'm thinking I may gut it completely and eventually build my own amp inside it. A project for the not-so-near future though.

Very cool thread.

I have just started building pedals. This is helping even with that!!

Your high pass filter schematic above might solve my overly bassy sounding fuzz construction.

Thank You

You're my absolute hero, man. I went to the shops to price some components and buy some enclosures today. Shopping for components here is a bit of a pain in the ass but the prices are unbelievable. They only want like starting from $12 USD for aluminum amplifier chassis, so I may well be building one of these next week. little aluminum stompbox enclosures from $3 USD. Not crappy stuff, either, perfectly durable.

Great write up. Thanks!

Replacing AA with a pot would give us a presence control, correct? Or is it not quite that simple?
