Hello.
Last night my T1 broken during a gig.
The problem is that the signal on the organ sounds is very very low. 
The bass still sounding loud and on perfect condition.
I'll be pleased if anyone could give me a clue for finding the 
problem.
Hope I could fix it, cos' would be difficult (and expensive) to find 
an organ with the same sound for my band.
Thanks in advance,
Sergio
