Afterglow-GTB 2 Posted July 18, 2016 Are these transmitters interchangeable for use with a G90? I could use a second TX as a spare/second guitar and see the V55 TBP12s come up quite often on Fleebay where as the Relay TBP12 less so... (Sorry if this has already been covered - I did search for it, honest!) Michael. Quote Share this post Link to post Share on other sites
NBell 20 Posted August 5, 2016 The TBP12 transmitters are the same radio, so yes both will connect and work just the same. The difference with the TBP12 transmitters for vocal systems are the Vocal Filters that are accessible within the transmitter. So with that said, make sure the filter is turned off when using for guitar ;) Quote Share this post Link to post Share on other sites
