I asked my amp tech about modding my JMP100 MkII MV so I can run an Amptweaker Tight Metal Pro straight into the power section, bypassing the JMP's preamp. I have heard this is how the pedal works best.
The tech responded enthusiastically saying he has done this mod many times. He said it is complex requiring another tube to be installed, something to do with signal level & impedance matching. He said I would also end up with some clean boost within the amp if I wanted to use it standalone and a serial effects loop. When comparing a Strymon Blue Sky through an amp with an effects loop (Krank K+) as against through the JMP out front, the difference was marked. The JMP is an awesome amp but this effect sounded WAY better in the loop of the K+. So getting a serial effects loop sounds good to me.
What type of pedals can/prefer to be used as a preamp like the Amptweaker? Is it worth getting this mod done?
