dave Bass 5
Can I just dive in here with a nod to the Aguilar DB924 - Aguilar designed the Sadowsky unit them started making their own. I use the 924 with a P bass and it adds a wonderful fullness to the tone. I had played a Sadowsky and was inpressed with the boost only controls it had built in. To describe what it does..... well it's not overpowering but you certainly know its there in a good way - I guess it enhances the tone! I've read people say that it sounds good at all settings but I guess that depends what you consider is too much treble.
Bad points
Its not footswitchable as an outboard unit, the Sadowsky is, but having tried the Sadowsky unit I was underwhelmed by it thought it was a gumtree sale and I have no way of knowing if the unit was faulty and personally I prefer the Aguilar. There is an on board version but that requires space for two 9v batteries- not thanks!
It runs off two batteries (no psu) they do last for ages and its well worth the slight hassle of changing them for the tonal boost they give.
You don't see them up for sale that often tho ebay is always a good starting point. I was gonna offer Dave a loan to try it out but sounds like you have been furnished with the SAadowsky. Hope your loving it fella.
