Maybe some of you other bass players have discovered the Eden World Tour DI pedal already, but it's certainly joined my select group of 'can't do without' pedals.
It's a combined preamp and DI unit with XLR and jack outputs so you can simultaneously amp and DI a bass guitar.
The control that makes it special is the 'Enhance' knob. Once you've used it your normal bass tone somehow seems rather 'ordinary'. Read some of the reviews and you'll see what I mean.
For bass players wanting that 'John Rostill' sound when the band plays a 'Burns Era' tune, there's a 'Mid Shift' push button that works with the Mid control. Set it to 2.2K rather than 550Hz and you bring out that Rostill 'click'.
