I had the same thought then realised this is a CMD121H. The crappy tweeters are on the CMD121P. The 121H has a different much higher quality compression tweeter.

Time to eat humble pie. Just checked and the 4 pot, 2 band pre-amp does indeed have a passive tone control. It's quite effective as well. @carlsim, I've sent you a pm.

I'll check tomorrow. I think you are right but I've never tried it.

Pretty sure the passive tone only works on the 3 band, 5 pot option. I've 2 of the ones you've highlighted and don't think there is a passive option. I'll check tomorrow but as I mentioned, you can easily add a passive control to any pre-amp.

I've 3 bases with them in. Love them. No colouring of sound and when set flat there is no difference between active/passive at all. You can add a passive tone control to any pre-amp and it's pretty simple. I'm sure I have a diagram somewhere. It's the way John East adds passive to his pre's.

I made my own stickers to go on a couple of basses that didn't justify a Luminlay installation and they've worked out well.

Works really well and you can make whatever size you like.

Tried the Hosco ones and they are nowhere near as good as Luminlay.

We'll that's buggered my plan of ordering some for the one bass I have that doesn't have them fitted.

The Drum Show is well established. They have been running it for a few years in Manchester, pre Covid. The Bass Guitar Show was a new venture. It may have been better supported if it could have been kept in Manchester as the UK Bass Show, organised by Stevie Williams, was a huge success until he dropped it to concentrate on recording with his new band.

Me too. About £15 and does the job.

Sure he mentioned on Facebook that he was there.

Including me as I applied with our drummer for a bit of a giggle. 🙂 Strange the things you do when you've had a few beers.

Result.

True, but it's the cost of the parts or in my case replacement board at £130 that made it uneconomical. £130+69+18 + VAT plus the cost of getting it to them and that's not far short of £300.

We'll the authorised service agent for TC is Real Electronics in Sheffield and they aren't cheap. They don't repair to component level, just board swappers. There are a number of posts on here about Mark Bass repairs as they are also the agents for them. Generally it's not economic. Here are their charges from a few years ago when I binned my MB amp as the repair was more than the amp was worth. £35 to diagnose the problem, which you get back if you go ahead. £69 fixed labour, £18 courier fee to send it back + parts all +VAT.

Drop @agedhorsea message. He is the Genz Benz expert.

Myself and Drummer applied. Story ends 😀

I'm a big Glockenklang fan and they are totally transparent when set flat. If you set them flat and switch between active and passive, there is no difference at all.

Most A/P switches are just double pole on/on switches. Using a triple pole gives you the ability to disconnect the battery as well.

If the battery connection is disconnected when the A/P switch is activated it won't drain the battery.

These cabs were developed for Guy Pratt for the Saucerful of Secrets gigs. He apparently wanted something modern but vintage looking, a bit like WEM PA cabinets. 2 of them with an ABM perched on top look just fine.

Not connecting the speaker shouldn't have caused any problems as it's a solid state amp and they are usually quite happy without a load. If it was a valve amp, that's a different story. The "no lower than 8 Ohms" is the lowest impedance of a speaker when you do connect it.
