| Not much info, Valco made amps for Gretch
Looks like the Expander G Came later when Gretch sold to Baldwin in 67 Valco went out of business in 68.
So any Gretch amp made after 68 is said to probably come from Premier or Multivox.
2 companys are mentioned to build gretch reverbs =
OC electronics or GSM
Kustom at one point was owned by Baldwin as well so the amp might be related to kustom.
Do you own the amp or looking to buy? if you own one already what is wrong with it? |
