    I dusted off the JMP-1 for a retube and took the chance to put together a demo showcasing what it does best.

    The more I use it the more I like it with the EQ all at 0. Classic!

    I used to love my JMP-1 and would love to get it back someday!

    I’m wondering if it’s worth the 500 bills to try one out.

    As opposed to buying another Synergy module? I'd say yes. For a start it's only available used... If it doesn't work out for you you should be able to get your money back.

    More to the point it's a great "rig expander. Run one in a loop in front of your Synergy it's the equivalent of a 100 different valve overdrive/EQ pedals in your rig pushing or cleaning up the synergy modules. I like the clean channels for this but OD1/2 have their own thing going on. And that's before looking at the multiple outputs, FX loop, speaker sim outputs, and extra midi functionality...

    Something I like about the jmp-1 the EQ isn't "interactive". My Mesa Formula Pre takes a lot more tweaking as it's a traditional tone stack. For anyone who hasn't found it yet you can pretty much "bypass" the jmp-1 on clean 1, bass shift "on", all 4 EQ to 0, gain/volume is a little guitar dependent but around 10 on both is a good starting point. It doesn't exactly "disappear" but I find what colour it adds pleasing. Think "valve buffer"!

    I only moved away from using this live because I didn't have a dedicated power amp; it was easier to bring a DSL 50 and a delay pedal rather than a rack AND the DSL as a power amp. I managed to achieve very similar tones with both units.

    Definitely a nice thing about the EQ, it makes tweaking very easy.

    As stated in another thread I've used the same JMP-1 for approx 20 yrs and 1000's of gigs.
    Its the only amp I own.
    I had the Voodoo Amps Platinum Mod done about 5 yrs ago and other than the lovely new Mercury Magnetics Transformer it was a waste of money. Their claims about tone and noise is nonsense, zero difference.
    I love everything about it and have no interest in changing.

    Please explain what you mean by "bypass".

    One of the best demos I've seen on the JMP-1. Nice job.

    I actually use my jmp-1 in series/parallel with other preamps. If you want to do that kind of stuff it's handy to know what settings are closest to true bypass. With Clean 1, Bass, Middle, Treble, Presence at "0", Bass Shift engaged, Gain/Volume around 9/10, output set to instrument level and the output pot about 12 o'clock I get outputs that are pretty much the guitar input buffered. Equivalent of bypassing a boss pedal for instance.

    Nice demo. It's hard to tell when not actually playing it, but is does sound a bit "stiff" to me. My ADA MP-1 is sort of the same way, but it can get spongy as well. Put it into a tube power amp and the stiffness goes away, though.
