Hello, all. I have an old EA iAMP 600--the big white one . I looooove the sounds I get from this amp when I play "modern" sounding basses--mainly my Hamer Cruise 2Tek w/Dimarzio UJ pickups. HOWEVER... I owned a Fender '62 reissue Jazz and never really dug the sound through this amp. The same bass sounded great through a Sunn 300 tube amp. (With my Hamer and some other basses I preferred the sound of the iAMP to the Sunn.) The other night I put flats on my P bass and have been...underwhelmed so far. Seems almost like there's too much "definition" to get that vintagey flats-on-a-P sound. Anyone else have similar experiences with the iAmp? Do I need to have my ears checked? PS: I play through a SWR Goliath Jr. III cab w/the tweeter cut back to about 25%.
