    This will be my first "proper," four-hole, Marshall-inspired offering. I figured a JTM-45 box would be the best place to start. Picking up locally tomorrow. Will be through a 3rd Power 1x12 Dream (hybrid closed-back) cab with a Celestion Gold that I have, but seller is also offering a Port City Wave 2x12 (standard size) with two V30s that I hope to snag.

    Beano album vibes, FTW!

    I had one of those years ago. Absolutely glorious when cranked up.

    Initial thoughts:

    (1) Bar none the most fun amp I've ever played through. Cannot stop smiling.
    (2) I'm gonna need a bigger cab...
    (3) Thank Christ this thing has a MV on it--and a darn good one, at that!

    Nice! Killer amp. And also... Is that a Beaufort Reverb over there? I just picked one up for a great price. Awesome blackface amp.

    It IS!

    It's an outstanding take on a Deluxe.

    I've owned two Clarks!

    Easily the best attention to detail I've seen anywhere! Just gorgeous work, and more importantly, they sound stellar!

    Didn't know about Sour Mash! Good to know.

    I'm going to pick up a Mojotone Bluesbreaker-style 2x12 extension cab next weekend in Charlotte. Loaded with Greenbacks.

    Cab's here!

    TBH...I've had the most joy playing roots-rock and blues rock in this rig thru the Tele so far!

    From the interior picks the circuit is a later 50 watt, more gain type of Marshall circuit. Not that that's a bad thing. Is that stock from Clark?

    Greenbacks, Tele, SG, Beano, Vibe Machine, Klon, and Flint. Yep, you've got most everything you need for that amp. Looks like a JMP50 not a JTM45 to me though. Filtering is too high, there is no tube rectifier, and split cathode.

    I have come to discover it's more of a JMP spec than a JTM45.

    It IS stock from Clark. Kinda confusing (at least I've been confused, for sure)--Clark Amps only has one name for all their plexi models as far as I can see (the "MTC-45"). Even his panels say "45" next to the power and standby switches. However, he will wire them a JMP spec at the buyer's request, and that's what this buyer requested. Considering (1) the price I paid, (2) the proximity I live to the original manufacturer, and (3) my general impulsivity, there was no way I could pass it up.

    There is more gain than I expected, but nowhere near brown sound levels. With the new-to-me 2x12 closed-back cab with Mojotone BV-25M Greenbacks (read up on those--interesting stuff), I like very much what I am hearing.

    Nothing wrong with a JMP.

    Yup, and it’s EL34


    OP, congrats man!!! Smart move going with that GB loaded Mojotone cab instead the one with V30’s. I just ordered a 212 from Mojotone that I’m going to load with a GB and an M75-PVC. JTM45 still a couple weeks out.

    It might not necessarily be a Beano rig but definitely some Cream tones in there. Cheers

    I've seen people stick el-34s in JTM45s before, but I also missed the split cathode on the first run through and added it to my post. It's a lead spec plexi.

    For sure! However, if I keep all controls at noon, then dip the mid knob and presence a tad, and play through that SG with the stock T-Type pickups, I can get close to some of the vibes on that record. Some more than others.

    Regardless, where it doesn't 100% land on a Beano-type tone, it lands on something else special and workable.

    Oh wow, it’s not even Bass spec?! So, 1987?

    Ya, I’ve definitely seen folks load JTM45’s with EL-34’s but the tube tag showing 34’s and no rectifier tipped me off that it’s not a 45. Thought maybe JTM50 with SS rectifier until I read your post. I see JTM50’s built both ways, SS/tube rec, KT-66/EL-34. I can’t remember when Marshall switched over to EL-34. JTM50? JTM45/100 I think???


    OP, you did say “proper 4-hole Plexi”. That’s what you have :aok
