SWR STUDIO 220

Έλεγα ότι δεν θα το δώσω ποτέ αλλά έχω γεμίσει ενισχυτές. Σε καλή κατάσταση για την ηλικία του.

Το preamp section του για όσους γνωρίζουν είναι ο προενισχυτής της Groove tubes, GTE 'Studio Tube' Bass Pre-Amp ο οποίος είναι πεντακάθαρος με λίγο έξτρα ζεστασιά από την 12Αx7.
Το preamp μόνο του αν το βρείτε είναι σπάνιο και pricey. Παρακάτω λίγη ιστορία.
