JMPGuitars Tremolo TMB Reverb Tube Guitar Amp

I created the tremolo TMB amp’s circuit design based on a request from a member on 18watt.com. The circuit came out so nicely, naturally I had to actually make one. After hearing it, I’m guessing I’ll be making more than one.

Here’s some improvised mediocrity to demonstrate this amazing guitar amp. The tube reverb and tube tremolo are built into the amp. The only FX pedal used in this demo is an Eventide Rose Delay Pedal in a few parts.

The first part of the demo is with an amazing @knightroguitars “Pioneer MS8” and the second half with a nice @kieselguitars HH2 (customized by me) ;).

What’s that? You want to see if it’s pretty on the inside too? That’s deep. Sure, check it out:

I Ain’t No Rat

I recently got a Vintage Reissue ProCo Rat in a trade, and even though I’ve never been a fan of the sound, I figured it would be fun to mess with.

And I’ve seen some crap. This is a USA made pedal, but who knows where the PCB came from, it’s just garbage. It has the thinnest traces, with poor bond to the board, and I can’t even think of a pedal I’ve worked on in the past 10 years that was this bad. Continue reading
