Mediocre Polymath

If the yellow-faceplate markbass gear has the same overall design as my LM250 Black line head, then the pots are small sealed units. When they get scratchy and shite, you have to desolder them and put in new ones as they can't really be cleaned. It's a pain, but the preamp board is at least relatively easy to remove.

EDIT: KNOCKING THE PRICE DOWN TO £50 because I've nearly finished building the replacement cab. This is a 1x10 cabinet that I built for myself a little more than a decade ago. At the time the options for speaker cabinets were more limited than they are now, as were my funds. I wanted a speaker that would fit into a narrow alcove in my house, like the line6 combo I was using at the time, but that didn't sound like total arse, like the line6 combo I was using at the time. It measures 34 cm wide (including side feet), 45 cm deep, and is 58 cm high (again, including feet). The cabinet is 18 mm birch ply. The speaker is a 10" Eminence Delta (can't remember the exact model) with a power handling of 200W RMS and a frequency response of something like 55–4,000 hz. The main speaker is paired with a 4" B&C midrange driver that's connected through a crossover, and extends the frequency response up to about 10,000 hz. It originally had a compression tweeter, but I quickily decided this to be scratchy and tinny sounding. I've found these two speakers give a decent half-way point between vintage rumble and hi-fi treble. It has connections for 1/4 jacks and Speakon on the backplate, but as the 1/4 jack output on my amp doesn't work, I can only vouch for the speakon. There's also a switch that bypasses the crossover and tweeter. It's covered in luxurious red leatherlette. I've been using it mostly at home for the last decade, but it does go out on gigs every now and then. When driven by my Little Mark 250 head, it has kept up just fine with the drummers I've played with, and it sounds good to my ears. At this point I'm guessing you're shouting "enough about your taste in tweeters, what's the weight?", and that's fair. I have been avoiding the subject. Due to some combination of unusually dense 18 mm ply, an oversize box and an old non-neodymium speaker, this thing is like a tiny rock-n-roll black hole. It weighs just under 20 kg. So yeah, if you're looking for a speaker to sit in a rehearsal space, basement, or shed with a reasonably strong floor, this cab could be just the thing for you. If nothing else, the handles (there's one at each end), corners and feet are decent quality and probably worth a few bob. Collection only, obviously, I don't want to even consider how much shipping would cost. I'm based in London SE4 and around most days.

The fact that this bass still hasn't sold is baffling to me. I used to play a BB604, and while its electronics were a little lacking (an issue that has very much been fixed here) it was one of the nicest playing basses I've ever laid hands on. Comfortable, relatively light, and incredibly stable (never had to touch the truss rod in six years and it would stay in tune for months). I make my own basses, I'm broke, I have far too many instruments in my not-large home already and I don't play five strings, but I'm still sorely tempted by this.
