General Comments
I see a lot of arguements about diodes and valves and to be honest, i dont really care, its the tone that counts. I CAN say that I have removed the br3 and other diode (to do an upgrade) and the clean is 100% unaffected which means that at least the cleans are all valve. The od channels still have the same gain but they lack the harmonic detail and clarity especially at low gain where they sound positively terrible. So yes, it does have diodes in the od channels but they are there to smooth things out and shape the overall sound, they are NOT the main part of the distortion.
Overall, I would recommend thet JMP1 to anyone looking for a live ready preamp with traditional Marshall tone. If you alreay have one and you are thinking of selling,... dont... you WILL miss it!
