It took some time, but finally I could pick up my Glockenklang 'The Passenger' 1x12" amp last Friday. After some serious pleasuring of my ears (and that says alot considering that it was me who played ) I can safely conclude it's the best combo amp I've ever encountered during the short but intense time I've spend as diciple of the low end. Both my Hartke and the Glock don't colour the sound of my basses at all (which I love, always after 'the Alembic sound') but while the Hartke could be described as 'clean' and sometimes almost sterile, the Glock is 'natural' and always very warm (and there's not a single tube in there!). I can easily understand why this amp is used so much for double bass too! I know we Europeans have an advantage when purchasing products that were made on this side of the pond, but should you ever encounter a good deal on one of these, don't pass it on, you'll be sorry!
