Thanks Luke, your experience sounds similar to mine with the Barts+ Bart pre - mid control just seems to add huge gain ,(not so much when I switch it to 800Hz TBF) I do get some decent tones out of it but am tempted to try the East, especially as she of the pots are on the way out (it's 20yrs old). It'll mean drilling out the holes to 10mm though (and it's a nice bass, Zon Sonus), so just building up the courage!
