Well I've been thinking about improving my bass tone... I have no effects 'cept an old Zoom ultrafuzz which I only use for playing Muse when I'm messing about... I'm learning a lost prohets song Shinobi vs. Dragon Ninja in my metallish band, and in the pre-chorus (I think) the bassist uses a weird phase-type wah effect that I think sounds awesome, but I don't have a clue how to get it... I decided to check out the flanger on my brothers Marshall AVT-100 just to see what it was like... And even though the effect was really weak on bass, through the clean channel I had such a clean warm tone slapping and playing fingerstyle, then with the mids boosted and then presence up I had an amazing plectrum sound... With the chorus on I had an amazing 80's slap sound, and with the OD-1 on and the gain down low there was a perfect grittyness to the bass tone... However, when I plugged my bass back in to my bass amp, for some reason thinking it was my bass that had decided to sound so nice, sure enough I had a brittle weak sound. Btw, my current amp is a Fender Rumble 60, my current basses are a defretted Westfield SB427, and a Traben Phoenix 4, though I'm building a 5 string with wenge neck, bubinga body (Growly for metal) and hopefully in November getting a Warwick Corvette 4 as my funk bass. Is this me experiencing the valve sound for the first time, or do I just really need some effects, EQ, compression, and a new amp?
