Yes, tried it out at the seller's place using an Orange OB-500. I don't tend to scoop my mids . Never have, when playing guitar or bass.
Thanks for mentioning. Had a quick look at your for-sale post and I'm afraid it's a bit too rich for my blood.
Since everyone keeps mentioning the HA 3500, I am definitely considering it. I'd certainly feel more comfortable running the cab within it's rated capacity (I know, I know, it won't hurt it if I don't crank it and I only spent £50 on the cab, but I'm just a big baby when it comes to risking gear), which puts me off the LH-500.
I'm still determined to try the TC BG250-208 when it's back in stock at Andertons, and I'll probably compare it to a Peavey MiniMax, to see how much I feel the extra 200 watts (at trying-out-in-a-shop volume, possibly not). I just have a good feeling about having a small combo that I can poke into a cab and get decent low end out of, but isn't as much of a pain to cart as the old Ashdown combo I used to have.
Budget at the moment is around £300.
Really appreciate everyone's feedback.
