Client satisfait :-)
M'ont permis de redonner vie à un préampli pour basse Peavey du début des années 90, avec à la clef une excellente réserve de gain, un son transparent et profond, et un overdrive doux et très musical.
Expédition sans souci dans un emballage soigné.

Très bons
En remplacement d' EH jaune, et comparé aux TAD ecc803s, ils sont plus détaillés, moins rentre dedans mais très bons chef d' orchestre. Je n' ai pas beaucoup de comparatif, mais ils sont pour l' instant mes préférés.
