petetexas Posted July 29, 2022 Share Posted July 29, 2022 Hi , Has anyone used the above onboard pre amp, and removed the BLEND control , so you have VOL , TREB/BASS (ganged pot) only ? Pete Quote Link to comment Share on other sites More sharing options...
Mcgiver69 Posted July 29, 2022 Share Posted July 29, 2022 Just remove the pot and connect the pickups directly to the connector. Quote Link to comment Share on other sites More sharing options...
petetexas Posted July 29, 2022 Author Share Posted July 29, 2022 Hi , I thought as much , and have asked Glockenklang, and Thomann, without any reply from either . Thanks for info, I feel a bit better getting one , and doing it now . All I need is a Volume and Tone ( I know it will be a ganged pot with treb and bass for the tone ) but thats all I need SIMPLICITY ON STAGE !

BassBunny Posted July 29, 2022 Share Posted July 29, 2022 (edited) I've got 3 basses with Glock pre-amps and just checked the wiring diagram and it may be possible. The blend circuit board is hard wired to the volume so a simple connection to the two wires going to the volume board should do it.

petetexas Posted August 2, 2022 Author Share Posted August 2, 2022 (edited) Hi , Had a reply from Thomann Tech ( who has been in touch with Glockenklang ) Yep , connect the + on the pup to 3 or 4 on the VOLUME pot , missing out the BALANCE control , and do not connect the MID pot .

petetexas Posted August 4, 2022 Author Share Posted August 4, 2022 (edited) While awaiting the Glock , l have fitted a bass pentatone ( 6 position varitone ) to the Gibbo.........very confusing connection info on line for this unit l - have asked de lisle for clarification. The different notch filters give the Gibbo quite a range of sounds , but l seem to have a connection issue, because l have lost the smoothness of my volume control !

petetexas Posted August 7, 2022 Author Share Posted August 7, 2022 (edited) Had reply from de lisle , l have somehow added an extra wire from volume pot to bass pentatone , hence the loss of volume smoothness (all effect at full turn) BUT , wired correctly as de lisle say , there is a large amount of volume lost as you go through the 6 positions , but the volume control works smoothly . I'm going to leave it with the extra wire , as l prefer the smoother sound , and less volume loss going through the positions . I will post both sketches later today , maybe someone with electrical knowledge can explain? Looks like the Glock will take a back seat for the time being .

petetexas Posted August 7, 2022 Author Share Posted August 7, 2022 Here are the two sketches of how the pentatone was wired ......... First one ( A ) correct to the instructions of de lisle..........vol pot works Second one ( B ) My extra cable ( balanced more across the six positions ( still some slight loss in volume ))Vol pot does not work correctly .....

BassBunny Posted August 7, 2022 Share Posted August 7, 2022 Diagram 1 looks correct to me except there is no earth to the volume control unless you've missed a wire off the diagram. A wire between the volume body and either the jack or earthing on the pentatone may be the answer. Quote Link to comment Share on other sites More sharing options...
Woodinblack Posted August 7, 2022 Share Posted August 7, 2022 Looking at the diagrams, 1 is correct (assuming the pentatone is wired like that), and 2 I am not sure how the volume is making any difference at all, other than working as a tone bypass a higher 'volumes'. There will be a loss of volume in some of the settings on the tone control, that is how a passive tone control works, it takes away more or less of the signal at different frequencies..

petetexas Posted August 8, 2022 Author Share Posted August 8, 2022 (edited) Playing Sunday afternoon , will leave it as it is (but take my Rivoli Bas as a standby just in case ) Thanks for input . Will put Glock preamp in if this turns out to be rubbish . Edited August 16, 2022 by petetexas Quote Link to comment Share on other sites More sharing options...
petetexas Posted August 16, 2022 Author Share Posted August 16, 2022 Hi guys , Used it Sunday at the gig , but as usual I kept switching to position 1 , then 3 , then 6 , then back to 3 etc etc etc just because they were there !..........too much messing about really . What I will say is that the sounds were all pretty good , all the way around the 6 positions switch . I might leave it on and try to improve the loss volume control , and settle on one sound . Last gig for the band anyhow, so no hurry . I`ll keep you posted Pete Quote Link to comment Share on other sites More sharing options...
