I've got it in my mind to buy a vintage Traynor combo (if a YBA-1 head was available at a good price I'd get that too). Right now I am considering the YGM-3 and YGM-4 (and am kicking myself for selling my '67 YGM-2 a couple of years ago!). I am familiar with the YGM-3s but have never seen a YGM-4. This is the same as the YGM-3, but with four 8" speakers. I've never seen or tried a 4x8 amp so was wondering if those who have could comment. Are they worth getting? Are there any drawbacks to the 4x8 format? Any benefits to it? With everything else being equal, would it be better to go for the 1x12 format or is the 4x8 perfectly good with the decision basically coming down to price and condition?
