I just have to say, i am completely blown away at the moment. I got to play a silverface fender bassman 10 combo today. 50 watts and just Gnarly as all hell. Long story short, found a ad on craigslist where a band needed a fill in bass player for one show. Go to the first practice and they said just bring my bass (Peavey Axcelerator 5 for this occasion) I have GAS so bad right now. Like, the mid punch of that thing blew me away. When i would go down to my low d or open B it left room for improvement, But good lord. I'm ready to just sell everything and get one haha. If i could figure out how to get that tone from my Fender TBP-1 i would never buy another amp ever again. Just wanted to share that with you guys, All input would be awesome. Manily if you have any tips on the fender TBP-1. I run it with a crown xls drivecore 1500. And my cabs very from two Earcandy Bassbomb 2x12's to the newer Fender Bassman Line of the 410 and 115 combo.
