Thank you for both replying. Reason I thought they aren't a standard is the G&L site says the American L2000 pots wouldn't fit the Tribute - 'Will not fit Tribute Series models without enlarging the mounting holes for the pots and using knurled knobs for solid-shaft pots available elsewhere in this store. Enlarging the holes for the pots may be done by a highly experienced technician using a reamer tool, as there is risk of damaging the body finish.'
In answer to your question Gary I think the USA models use CTS pots so that would be the obvious upgrade but it's a pity it's not a straight swap. Out of interest did you order direct from G&L?
BassBunny, thank you giving me the values of the pots, they should make life a lot easier for sourcing replacements! I'll have a look at the Bourns range as they have a really good rep.
Frustrating thing is I've hardly used the Tribute for this to happen and I've never abused her in any way. Suppose just bad luck but I've heard of others having problems with the standard Tribute pots too.
Thanks for your replies, much appreciated!
