This Hartke is a recent acquisition but I’m going to go with my also recently arrived MXR deluxe chorus as the MXR has bass and treble eq which I’ve found helps a lot, especially on my fretless but I'll add that the Hartke is a very nice sounding chorus The pedal is in as new condition, runs off 9v battery or mains power (not included), the plus being with using a battery is that Hartke have an easy to access battery compartment, no fiddling with unscrewing the base plate to change batteries at a gig.
and so selling at £30 for the Hartke pedal posted in the UK.
Thomann website has a few sound examples for this pedal and it sells there at around £59 plus postage on their website.
