I bought a DHA DI-EQ pedal from a fellow BCer and I absolutely love it.
I've tried all sorts of different pre's / DI boxes (Ampeg, Trace Elliot, MXR, EHX, Sansamp) and this is fast eclipsing the lot. The balanced DI out is super-clean, switchable between ground, lift and float, and the EQ is really musical.
Even though it's solid state it has a real warmth to it, and can do pretty much any clean tone you could imagine - everything from bright, blistering slap to old school thump and thud.
My best purchase all year (and there've been a few...). It's small enough to fit in a gig bag and can be powered by a 9v battery as well as a standard 9v Boss style adaptor, so it's ideal for jam nights / acoustic performances. I've even used it to play for a couple of shows and just gone straight into the PA and have always had a great tone.
Like all DHA products it's built like a tank, but much easier to operate. For £70 new it's a real no-brainer - I'll probably never go to a gig without it again.
