I have a question about my SR1345: today I opened up the electronics compartment and made these pictures of the preamp:
View attachment 4864722
This first picture shows that there are two INPUT contacts - the right labeled 0dB and the left +6dB. The jack in my bass was inserted into the right one 0dB. Changing the Inputs did not made any difference... My initial thought was, that the outsignal should be different by 6dB when changing the connector, but there was no difference between the two.
View attachment 4864723This second picture shows the output connectors (middle connector removed to make the labeling readable): it schows two outputs VM3 Out and BEQ3 Out. My bass was connected at the lower VM3 OUT, but switching to the other connector didn't change anything.
Can anyone give me some insight how this options are meant to work?
To give you the full picture, I attached two recordings of the bass:
Active-Passive_Comparison_Ibanez-SR1345.mp3
This first file compares the signal from my bass from active to passive - all controls at noon in active mode, in passive mode tone blend fully open. Beside the huge difference in sound there's also a huge level difference between both modes.
Active-Passive_Comparison_level-matched_Ibanez-SR1345.mp3
Even in this level-matched comparison (active first, then passive) the sound difference is more than obvious.
My question to all SR owner with the latest electronics (3 frequency switchable mids): is this similiar to your basses? Or do I have a banana?
Edit: I found another thread about this preamp (
The mysteriously unreferenced current model Ibanez 3EMP3LD EQ) and according to this information directly from ibanez my bass was wrongly setup as the output was connected to the VM3 Out connector but should be connected to the BQ3 connector. And after I switched it to this connector the output in active mode is much less muddy. But the level difference stayed the same as in my examples.
