I have been searching the archives over this but don't seem to have found quite the answer I want. I am using a SVT-3 pro head which has a nice creamy tube sound to it anyway. If I max the gain and the tube gain I can get quite a good overdrive sound. However: a) Constantly changing the amp settings can be a pain in the Arse. b)I desire more OD than can be achieved by this method alone. c)I seem to lose a certain amount of attack. This may be a problem inherent with OD but the volume level seems to waver and lessen on attack to some extent. Not sure if this is normal. I am interested in a stompbox only. Reading various posts the Fulltone Bassdrive and the EBS Multidrive seem to be favourites. (I was interested in the budda phatbass but according to Biggie I wont get much more out of it than my SVT). My criteria are: 1) PLENTY of OD! I want to go beyond the capabilities of my SVT. 2)Control. I like to tailor my sound. (though if a pedal has a blinding sound I don't mind sacrificing tweakability for sound quality [the philosophy of a phase 90!]) 3)A GOOD SOUND!!! Creamy-growly tone! I'm using a Washburn XB600 (active) and a passive Aria pro 2. I appreciate that this is a personal taste matter but I really want your opinions. I checked out the Harmony central reviews but they dont quite answer my questions. ...and I dont have the luxury of sauntering down to the music shop and trying them out! Please help un-befuddle my head!
