When I arrived at this afternoon's rehearsal I realised that I had forgotten to bring my pedalboard. D'oh! Rather than use the non-master-volume single-channel amp I had brought with me, I plugged into the rehearsal room's Blackstar HT Club 40. I set up the drive channel with enough gain (just 9 o'clock on the dial) to go between crunch and crunchier using the guitar's volume control. I'm not a fan of Blackstar amps, but it sounded surprisingly good. For various reasons I wouldn't choose to buy one, but kudos to Blackstar for making something that works.
