Thanks all for the prompt responses. I didn´t know that about UK & Spain coming into EU 230v. Actually I´ve since tried the same setup at home (2880 stereo in two guitar amps) and problem didn´t occur. So perhaps there´s something up with the electrics in the rehearsal room – will try to prove this as root cause next then. Cheers!

Update on this…in the end I bought a T-Rex Fuel Tank, to supply other pedals primarily but which also has a 12V DC 500mA output that seems to work with the 2880. Solves the problem I had previously with the click track interfering with loops at least. Bit worried still though since the 2880 ships with a 9v DC 500mA adaptor, and perhaps feeding it 12V for an extended time is going to knacker it (although I’ve read elsewhere this might be safe enough). What I really like to by though is a genuine EHX replacement Euro adaptor – anyone able to advise where I might be able to get this from? I’ve contacted my local dealer in Barcelona already but unfortunately they seem only interested in selling me new pedals. Alternatively I’d look for a different brand solution to provide 9V DC 500mA (in fact using the T-Rex doesn’t really work for me since the patch cables are short & I like the 2880 on a stand at arms reach while playing….).

Thanks again for any handy hints…cheers!
