Indianrock2020 Posted February 13, 2016 Share Posted February 13, 2016 HD500x with vintage pack. I've created patches with this Jazz Rivet ( Roland Jazz Chorus ) amp model that sound good and others that just have no volume and sometimes distort with nearly the same setup as the good patch. Almost all of my patches these days are dual amp, dual cab -- and in this case they're both Jazz Rivet with the Jazz rivet speaker cab and same microphone. Typically Noise Gate to Red Compressor to dual amps to mixer to delay to reverb to volume pedal. For these clean patches I don't even add an overdrive. When a patch with this amp decides to sound bad, removing one of the two amps doesn't help. Quote Link to comment Share on other sites More sharing options...
AlexKenivel Posted February 13, 2016 Share Posted February 13, 2016 Is there a question in here? 1 Quote Link to comment Share on other sites More sharing options...
Indianrock2020 Posted February 13, 2016 Author Share Posted February 13, 2016 I'll resist the temptation. Yes there is a question. Has anyone experienced that and if so how did you fix it? Quote Link to comment Share on other sites More sharing options...
AlexKenivel Posted February 13, 2016 Share Posted February 13, 2016 I've noticed the JC is a little on the quiet side, but nothing the mixer and EQs couldn't fix Quote Link to comment Share on other sites More sharing options...
Indianrock2020 Posted February 13, 2016 Author Share Posted February 13, 2016 I've been trying compressors and have pushed the mixer as high as +7 but haven't tried using EQs to boost output. Have you found any particular speaker cabs or mics that help this amp? Seems like I noticed something similar with the new Vox AC models like the A30 Fawn Nrm and A30 Fawn Brt. Not odd distortion but just low output. The regular AC 30 model doesn't suffer from this as far as I've noticed. I use a different patch for every song so getting the signal level to the mixer similar is important. Quote Link to comment Share on other sites More sharing options...
DunedinDragon Posted February 13, 2016 Share Posted February 13, 2016 I absolutely love the Jazz Rivet and the Jazz Rivet cab from the vintage pack for jazz, R&B, funk, and clean BB King style blues. I use it quite a bit for those types of songs in our songlist and each song has it's own patch (I don't re-use a patch from one song to another, each one is slightly customized). It can be a bit light on volume, but no worse than some of the other amp models. I'd say it's pretty easily equalized with either mixer volume or Studio EQ at the end of the signal chain. I only use a single signal path in my patches with the Jazz Rivet and I would suggest you might have an out-of-phase issue if you hadn't mentioned removing the dual path and it not fixing the issue. The rest of your setup sounds pretty standard although I rarely use compression on mine and if I do it's something very simple like the Vetta Comp for funk style stuff, but I don't use it to boost volume...just light compression on the guitar. One thing you might try is rather than create the patch from scratch, take one of your good patches and copy it to a new slot and make your modifications to that patch. That way you could better identify what is introducing the difference in the behavior. 1 Quote Link to comment Share on other sites More sharing options...
Indianrock2020 Posted February 13, 2016 Author Share Posted February 13, 2016 Thanks for the feedback... One other thought came to me. On the other patches which typically use dual AC 30 TB or dual Marshalls etc I've been setting the channel volume on the amps all the way up, the "master" amp parameter all the way up, the mixer usually 2-4 db up, a compressor like the red comp near the front of the chain with 50-70% on the level and a volume pedal as the last effect in the chain set to min 70% and max 100%. (almost always in the full up 70% position) Amp drive is usually from 30-50% and for what I play I rarely need to kick on an overdrive. I'm thinking that when I use an amp model with less output it can't keep up with the settings on these other patches. So I could back the channel volume on the Vox/Marshall patches down to 50% which just means the sound guy will have to boost the gain on my channel. The real Rivet has two 60 watt amps so its not clear to me why it should be "quieter" than dual AC30 or dual Marshall Brit J-45s. As far as cabs and mics, if I'm not sure I use identical cabs/mics for the two amps to avoid phasing. Otherwise I may pick a combination MeAmBobbo has verified http://foobazaar.com/podhd/toneGuide/cabsMics#dualCab-faves Quote Link to comment Share on other sites More sharing options...
BBD_123 Posted February 13, 2016 Share Posted February 13, 2016 If you've got the channel volume all the way up and you have effects post-amp (especially eq.), you will get horrible digital clipping. I tend to leave channel volume at ~45% and gain stage the rest of the signal chain (including the mixer) to compensate. http://foobazaar.com/podhd/toneGuide/setup#gainStaging Quote Link to comment Share on other sites More sharing options...
BBD_123 Posted February 14, 2016 Share Posted February 14, 2016 Indianrock2020 You've made me go back to the Roland model and the fact that I get a slight, unpleasant treble clipping sometimes. Try setting the input impedance to 22K. This fixed it for me. Quote Link to comment Share on other sites More sharing options...
Indianrock2020 Posted February 14, 2016 Author Share Posted February 14, 2016 I'll try it but would probably want to set that input impedance to "preset input setup" since almost all of my patches are set to impedance "auto" and Global Quote Link to comment Share on other sites More sharing options...
BBD_123 Posted February 15, 2016 Share Posted February 15, 2016 Indianrock I can get a clean, reasonably loud tone from this dual amp setup: /JR A - Vetta Juice -\ Noise gate - - Mixer \JR B - Vetta Juice -/ Where: Impedance = 22K Noise gate = default Amps = default *except* Master Volume at 50% and Channel Volume at 45% for both Vetta Juice = Amount 0% Level 100% Mixer = Path A and Path B: Level 12dB Pan Centre Possibly the way forward would be to do as you suggest and dial back the other patches until they level with the JR patch(es). 2 Quote Link to comment Share on other sites More sharing options...
BBD_123 Posted February 15, 2016 Share Posted February 15, 2016 Sorry about the formatting stuff-up. Perhaps this will work better: /JR A - Vetta Juice -\ Noise gate - - Mixer \JR B - Vetta Juice -/ 1 Quote Link to comment Share on other sites More sharing options...
