aye it's a 3 year warranty they have. Got the amp home last night, sounding far healthier now. Glad that I changed the tweeter over, it's much quieter than the stock tweeter.

Update: In the end I got in touch with Real Electronics, as the feedback issue was doing my head in. They picked up the amp on Monday, switched the voltage over, and discovered it was the preamp that needed replacing. My amp is now on it's way back up the road. I really can't fault them on their high level of service.

When I first bought the amp, I sent it back to Thomann within a few months as it stopped sending signal to the speaker (DI still worked though). And then a year or so later the DI failed whilst the Amp continued to function otherwise, it was sent back again just before the warranty ran out. Now when I turn the EQ controls beyond say 3 o'clock (no gain, volume or anything plugged into the input), I get feedback in whichever tone is being adjusted. I'll post a video later.

Cheers for the advice guys, I'll email Markbass to see if they have any further comments on the voltage issue. If I'm able to post video, I'll try put up some clips of the sound issues I'm currently having. It is just outwith the 3 year warranty so I'm quite happy to take it to my own repair guy from now on instead of shipping it for a service.

Hi guys, Having a few sound issues with my Markbass CMD121P at the moment, and looking to eliminate any possible issues before taking it to my amp technician (100 miles away as I live in the middle of nowhere). I've already invested in a HT-30 tweeter to solve the well known tweeter issue. Hoping to install it this week. However, my main concern is the fact I bought the amp from Thomann, and not a UK shop, and therefore the voltage has been set for Europe and not the UK. I know for most electrical items this would not be an issue, but apparently it is if you buy a Markbass amp. Whilst having a nose inside the amp, I noticed this bit.... [attachment=230289:image1.JPG] Is it a simple case of move the jumper from the middle (CN3) to the bottom (CN1)? Or is there any other steps I need to follow? Cheers, Richard

[color=#000000][font=verdana, geneva, lucida,]Hi, wondering if anybody has had the same experience as myself with the Markbass Mini CMD 121P LM3 Combo.[/font][/color] [color=#000000][font=verdana, geneva, lucida,]On Friday evening I went to use the amplifier. However, there seems to be a problem with volume coming from the speaker. I plugged a cable into the Line Out socket, and it does provide a signal to a mixing desk and works fine through a house PA. After maybe 30 minutes, the speaker suddenly comes to life for all of a few minutes, and then cuts out again. I have tried the bass amp again yesterday & today, producing the same results.[/font][/color] [color=#000000][font=verdana, geneva, lucida,]Normally I just run the amp on its own for small pubs and clubs. If it is being used for anything bigger, I use the Line Out. It has never really been played at a loud volume, so I am a bit miffed if I have blown the speaker.[/font][/color] [color=#000000][font=verdana, geneva, lucida,]If anybody could shed some light on this issue I would be very grateful. Thanks.[/font][/color]
