samuelcroberts Posted January 8 Posted January 8 Hi Guys, The piezo pickup on my 2009 Rob Allen MB-2 has developed a ground/shield hum issue. Looked at the piezo transudcer itself and the silver coating has started to corrode and peel back, which is most likely the culprit of the problem (everything else has been checked). Does anyone know what model the original or updated Fishman replacement is? Is it a Fishman Matrix like this (https://www.thomann.co.uk/fishman_acoustic_matrix_serie.htm)? I have emailed Rob Allen (and Bass Direct, who have also emailed Rob), but haven't had a reply yet. Just thought I'd ask on here in case anyone has the answer straight away. Many thanks! Quote
ikay Posted January 8 Posted January 8 There's one (listed as sold) on the Rob Allen accessories page here - https://www.roballenguitars.com/acce/4-string-piezo-electric-pickup It looks very similar to the one on the Thomann link. It seems to come in wide (3.2mm) or narrow (2.3mm) formats so measure before you buy! Quote
samuelcroberts Posted January 8 Author Posted January 8 Oh I missed that on his website... Only issue I have is that my MB-2 is a 5-string. The Fishman Matrix on Thomann is definitely the right width (3.2mm), but it's the length I'm not sure about. The cavity length on my bass is about 86mm long, but there doesn't seem to be a measurement for the Fishman pickup lengths anywhere - just width... Quote
samuelcroberts Posted January 8 Author Posted January 8 So I have managed to temporarily solve the problem with some shielding tape and kitchen foil wrapped around the damaged/corroded area of the pickup... Bit Heath Robinson, but it works! Did hear back from Rob Allen as well, who are going to source a new pickup for me. Cheers! 4 Quote
