I've got hold of the above amp. Well, it's actually the power amp section of what was once a Laney bass head, combo or whatever. The preamp side is missing. Someone has taken the power amp and built it into a (unsuitable) box with a speaker to make a bass guitar combo. I'm thinking of utilising the DP300 as the basis of a PA. The question is, can anyone please tell me the input sensitivity of this unit? At a pinch I could measure it but I thought I'd ask here first. Cannot as yet get the Laney people to tell me. John
