Agreed. That's why I sold my JCA20H and bought a JCA22H. Besides having a second overdrive channel (SLO circuit) it also has an effects loop. My delay and reverb are in the loop. I'm going to have to mess with the reverb to find higher gain settings I like or just leave well enough alone.
One thing that freaked me out at the store is that it has a "soft touch vacuum switch" which means it doesn't click. I feared it was bad right out of the box. Since I live 1/2 hour away I wanted to try it out before I left to make sure it wasn't DOA. Thankfully there were no problems whatsoever.
