Can the Soldano SLO-30 Dethrone a Marshall Legend?

Can the Soldano SLO-30 take on a vintage Marshall JMP 2203?

BuyOrBorrow Music put them side by side in a full-stack, no-holds-barred amp shootout—and the results were shocking.

Dave, our founder and longtime Marshall collector, has sworn by his 1977 JMP 2203 for decades. It's the amp he calls his desert island tone—loaded with mustard caps, EL34s, and that unmistakable late-'70s bite. But when a VIP member requested a Soldano SLO-30, we couldn’t resist a comparison.

In this video:

🎛️ Clean, crunch, and full overdrive tones from both amps
🎸 Real playing with real mic’d tones—no amp sims, no fluff
🔄 A/B shootout with identical cab, mic, and guitar setups
🎧 Dual-mic stereo mix: SM57 + AKG C414 in figure-8 mode
🛠️ Honest thoughts from a Marshall lifer who didn’t expect to be converted

The SLO-30’s crushing low end, dynamic feel, and jaw-dropping sustain raised serious questions—even for someone emotionally attached to the Marshall. From massive lead tones to surprisingly usable cleans and one of the best crunch sounds we’ve heard, the SLO-30 is every bit a modern classic.

🎧 Tip: Use headphones to catch every nuance of the tone.

This one’s close. And maybe a little controversial.
