I hadn't heard of the JHS pedal before this thread so always nice to hear different options and that price point is spot on The tone is exactly the same, just lower in volume. I mean that's all that's happening. I'm lowering the volume after my main dirt (either a Jekyll & Hyde on green mode or an MXR Modified OD). Now, in an ideal world, I would get a volume boost and gain boost for solos but there's always a compromise with every amp, I find. So it's slightly more gain than I would like for rhythm because the attenuation is coming after the dirt but it's very workable. I've tried adding gain for solos with a boost/ overdrive/ distortion but this amp gets too saturated even with the gain on the 'boost' pedal close to zero. The FX loop on the Vintage Modern is like no other amp I've used. EQ as a boost through it sounds awful (no volume boost btw) but an overdrive pedal through it sounds great. Madness. YRMV.
