petetexas Posted October 29, 2017 Author Share Posted October 29, 2017 (edited) Cuzzie and Phil T , Can I ask you both if your Bass Guitar drives the input to distortonon the low E string ? If I put my Stingray into the HD75 , it distorts , even with the Volume rolled back about 30% , if I really hit the string . I have sent an email to Hartke asking their opinion .

Phil_T Posted October 29, 2017 Share Posted October 29, 2017 No, I've used it with both a passive and an active bass and never noticed any distortion. I usually have the volume around 1 to 2 o'clock but it's clean up to maximum. Quote Link to comment Share on other sites More sharing options...
Cuzzie Posted October 29, 2017 Share Posted October 29, 2017 I have made mine fart out when pushed, vol wasn't maxed on it, but i did have a pre amp pedal. Its worth emailing them to find out, but their cones are a bit stiff so it does not surprise me it farts, but yours seems to be doing it a little early. Be worth finding out what they say. Is this just your practice rig or what you maybe take out? Quote Link to comment Share on other sites More sharing options...
petetexas Posted October 30, 2017 Author Share Posted October 30, 2017 (edited) Hi guys , What I failed to tell you , is that this amp is bloody loud ( got for bedroom practice - did not realize how loud ) the volume is not even at 1 on dial . The volume pot seems to be on the edge of either on or off ( just under 1 on dial ) I have found that if I turn all the EQ sliders to -12 , it does not distort , and the volume control works much better - up to about 3 or 4 for a reasonable bedroom volume . Tried it through headphones , seems ok . I will take the combo to rehearsal tomorrow night , and try at volume to see if it distorts . Will let you guys know . Maybe I am expecting too much for a 75w efficient combo , to play at a quiet bedroom level ? I never get this problem with my LM800 and G&K cabs in the house - but then again the LM800 has a gain control at input .

petetexas Posted October 30, 2017 Author Share Posted October 30, 2017 (edited) Hi Guys, Problem solved .....................I plug my Stingray into a Behringer Micro Mix and turn the signal level down ( mini 4 channel mixer ) , then into the amp . This stops the output from the Stingray , overloading the input on the HD75 . I`ll still await the reply from HARTKE to see what they say Pete Edited October 30, 2017 by petetexas Quote Link to comment Share on other sites More sharing options...
Cuzzie Posted October 30, 2017 Share Posted October 30, 2017 Remember also about the Hartke EQ Flat is Bass and Treble at 3 and mids at 10 Dunno if that helps Quote Link to comment Share on other sites More sharing options...
petetexas Posted October 30, 2017 Author Share Posted October 30, 2017 Hi Cuzzie , Thanks for the suggestion , but I`m a bit confused ...........Bass +/- 15,,,Treble +/- 15,,,, Mid +/- 15 then there is the graphic freq all +/- 12 on HD75 Are you saying that i try and put Bass and Treb at +3 and the Mid at +10............................... ? What I have done is put the "smiley face" on the graphic eq , and that has helped ....made it smoother , but hit the strings hard -lower register - and it still distorts . I still believe its the input signal - miss match . It will be interesting to see what Hartke say,,,,,,,,,if they get back ! Pete Quote Link to comment Share on other sites More sharing options...
Phil_T Posted October 30, 2017 Share Posted October 30, 2017 I noticed that a relatively small bass boost on the active bass would cause the speaker to flap so it looks the same sort of issue Quote Link to comment Share on other sites More sharing options...
petetexas Posted October 30, 2017 Author Share Posted October 30, 2017 Hi Phil T, Yes you are right , wound the bass on the Stingray back to mid position ( no boost or cut ) and its improved it a lot . I always have the bass full on and bring the treble in to get just enough bite , playing live with the Markbass and G&K Cabs Markbass set at 12 o`clock on eq. I can compensate now with the eq on the Hartke for bedroom practice . To anyone reading this , the HD75 is VERY VERY loud ! ! ! ! ! ! ! it could probably do small gigs ( 40 / 50 people ) Decided to keep it now , thanks again to all the input [u]Phil T[/u] and [u]Cuzzie[/u] Pete Quote Link to comment Share on other sites More sharing options...
Cuzzie Posted October 30, 2017 Share Posted October 30, 2017 Glad to hear that and let the fun begin! Quote Link to comment Share on other sites More sharing options...
petetexas Posted November 1, 2017 Author Share Posted November 1, 2017 (edited) Correction to my above post , this amp will NOT do small gigs IMHO , unless you want the sound of Elvis Costellos Bass player at the start of PUMP IT UP ! To keep it clean ( using a 2 band eq Stingray ) you not only have to keep the bass control 12 oclock , but also the volume rolled back to 50%, or it distorts . Because you have the volume rolled off , you dont get enough output for a gig ( IMHO again ) I bought this amp for bedroom use, and with "tweeking" its ok . I have had a reply from Hartke , after sending them a second email , and they quote " we have not receied yor previous email" ? I have now sent another ( 3 in all ) we will see .

petetexas Posted November 3, 2017 Author Share Posted November 3, 2017 Udate................ After a number of emails to and fro with Hartke over the last few days ( what are the amp settings , what are your bass settings , have you tried with other basses , are the batteries new , try changing the leads etc )........they have come to the conclusion that I should get it to an authorised dealer workshop , to get it checked out .

petetexas Posted November 4, 2017 Author Share Posted November 4, 2017 Have built myself a little signal pad - 250k log pot with treble bleed cap and resistor - plug bass into it , before going into amp and turn it up ( padding the signal ) now I get NO DISTORTION . Shows that the input of the amp is distorting . I sure wont buy any more Hartke amps , or any other , which do not have a gain control at the input My Stingray works perfectly with my Markbass LM800 , Warwick LM1000 , Warwick X-treme and my Ampeg PF500 - all of which have a gain control at the input .

Cuzzie Posted November 4, 2017 Share Posted November 4, 2017 Well worked out buddy, sorry you had to go through all that. Quote Link to comment Share on other sites More sharing options...
petetexas Posted November 23, 2017 Author Share Posted November 23, 2017 (edited) Just had the chance to try two Passive Bass into the Hartke HD75 . A Tokai Thunderbird , with Humbuckers , and a Fender Jazz NO DISTORTION AT ALL ! Why don`t Hartke put a gain control at the input , to pad the input signal ...........I suppose its down to cost , but they have certainly lost a customer for any future purchases with me .
