Marshall JMP-1 Tube MIDI Guitar Preamp

Sound Quality

Yes , it´s noisy , even with humbuckers . Buy this if you want that crappy Marshall tone , so its excellent ! Brytal ? HAHHAHA . The distortion is the weakest possible ! Too bad for an expensive rack product .


At least , the thing is strong . About the tubes inside , don´t worry . They make no difference . But it doesn´t matter , a hard-made preamp which sounds bad ...

General Comments

I´ll answer now a "famous" question : JMP-1 VS Triaxis .

Try the Triaxis !!!

I spent MUCH money buying this JMp-1 , and I felt bad after 5 minutes playing !!!! I´m really TOO SAD , even Taiwan made pedals can sound much heavier than this one .
