Yep, the FX loop works using a single stereo cable input to that single jack. The other end of the cable has two mono jack plugs, one is FX send and the other is effects return. I hope that makes sense.
The markets a nightmare...not sure what is going on but some great deals if you are a buyer...a friend of mine got a Hiwatt custom 50 1x12 combo for £450 (one of the new ones) in mint condition...Ive got a Washburn Custom Shop CTS guitar in white with Seymour duncans which Ive only been offered £375 for or £450 px... Another guy I know bought a TSL100 head in mint condition for £225!!! Crazy!!!!
If I could get the cash together I would have the matamp in a heartbeat but if I bought it at £650 my wife would have my heart stop beating when she realised the cash (or Kids) had gone :-)
Yep, the market is depressed for second hand gear, and I am not letting stuff go for the sake of it, so might have to pop some stuff in the loft until things pick up. I am fortunately not desperate for the cash, but failing to sell stuff is preventing me from buying other stuff, so this depressed used market (for sellers) and great deals (for buyers) might also have a knock on effect on the new market.
