Hi guys. I have a Lindo Zebrawood with a TOPS-4T preamp installed. When I was busking tonight a pint got spilt on it and bye bye preamp. I am on a mega budget and I know the TOPS-4T is £25 but I found this which seems better, at least on face value. Basically I want a preamp which fits in the whole, works and ideally has a chromatic tuner on. Any opinions?
