Alright, so here is my situation: Up until last night, I’ve been running an Ampeg SVT-VR into a 212 cab. Ran as usual when I plugged in a couple nights ago. Plug in last night for band practice, and my amp sounds like a banshee (not in a good way). Looks like a power tube is out at least, and there may be more issues — a future visit to my local amp guy is in store, to say the least. Regardless of the issues with the amp, last night did make up my mind to get a class D as — at least — a backup amp, if not my gigging amp. My board is currently: tuner > DG Super Symmetry Compressor > Rusty Box > MDB-1 > TFR > Rainbow Machine > DOD FX72 flanger (the SS and RB are always on). I play a passive P-bass, and generally have a post-rock/stoner rock type sound. Knowing this, any thoughts as whether I should pursue a Quilter BB 800, Tonehammer 500/700 or one of the Mesa Subways? I’m also considering just running the the RB into a power amp. Thanks in advance.
