OK 18 Watt gurus I have a question. My new (used) Blockhead 18 watt combo sounds great, but I've noticed a couple of things. It seems like the 1st side (Volume and tone only) is relatively quiet. The 2nd side (Tremolo side) is twice as loud, but the tone control doesn't seem to do very much if anything. Is this the way these amps normally are or does it sound like a mod to beef up the drive on the tremolo side? I LOVE the sound of this amp, and I doubt I'm going to change anything, but I'm just wondering what is normal with these guys. Any help is greatly appreciated!
