My Music Store has an Ashdown Klystron 400 Combo (2x10) to sell (its in commission). The price-tag is EUR 700, but I reckon you could get it for 600. The Amp seems very similar to the ABM-Series. I've read a review in Bass Player 6/98 which was very favourable. Any experiences with that amp. Can it stand up to the ABM-Series? Would you consider it a good deal? Thanks for your opinions!
