Had an 1979 L5 with two EVMs, a 12s and a 12L for six years. Sold it to get a Marshall and regretted it literally the next day. The new owner wouldn’t think about selling it back to me.Yeah, being a circuit geek, and seeing what's going on with the L5 (via the schematic), I can understand why the OD with that amp would sound so good.
The Aion L5 pedal also no doubt has the advantage of being usable with power amps that weigh considerably less than the original L5 amp does!
It was a monster to carry around, but sounded great. Recently, I got the aion L5 kit, but for lack of the EVMs, it just doesn’t sound the same. I have since switched to not selling anything anymore. Once bitten, twice shy
