I just had a Demeter preamp put into my Roscoe SKB-3006 and the bass just came alive! I had the Bartolini 3 band with this bass and I feel that it just squashed the sound. It's just too compressed for the bass. The Aguilar wasn't an option for me because it's too noisy. The Demeter is incredible. It sounds open and clear and it made the bass more dynamic. I'm very impressed with this preamp in my Roscoe so I just wanted to share and suggest it to other Roscoe owners. I'll post a pic and a sound clip very soon. The bass did need another hole for the eq but it turned out looking great.
