edstar1960 Posted June 3, 2015 Share Posted June 3, 2015 I tried to set up my JTV TMOD-5 (neck pickup) model to be similar to my Fender 60's Player Tele neck pickup. I had my JTV connected to my HD500 with VDI and my Tele connected via 1/4" Guitar In. The HD500 connected to my PC via USB and Windows HD running. I had L mono out going to a mixing desk connected to a reference amp connected to Tannoy Reveal monitors. I just wanted to get the model strings balanced and sounding similar to the real thing - I didn't think I could get them to sound identical, just similar. So I was just using the same CLEAN sounding amp model patch in the HD500 for the comparison. Both guitars had Volume and Tone controls on Max. First off, I was surprised by how different they both sounded - the Fender Tele with rich warm notes on the 3 low strings and treble attack on the high strings but the JTV model just had high treble attack across all strings. So I looked at the GUITAR-IN-Z setting and it was set to AUTO. So I tried removing the fx blocks before the amp in the patch and when I was left just with the amp, I was getting a brighter sound but still nowhere near as bright as the JTV model. So I tried manually setting the GUITAR-IN-Z value and even with it on the highest level of 3.5M the Fender Tele did not sound quite as bright as the JTV model. It was getting closer but still far enough apart to easily be able to tell the difference. Nothing more I could do to adjust the Fender Tele tone, so I looked at options for the JTV model, and the only things available in Workbench HD are the Volume pot resistance value and the Tone pot resistance and knob position. As I always have my Tone on max, the Tone pot value was not going to be of any use, unless I decided to save a lower Tone knob position with the model. This prompted me to ask "why can't I set the input impedance for the Variax VDI just like I can with the Guitar In?". Surely that would be the best option? But it's not available. So the next question "why is it not available?". My testing with the GUITAR-IN-Z showed that those changes made a big difference to the tonal input of the guitar. Surely we should be able to do the same with the JTV? Or if not, then surely the JTV models should be very similar to the equivalent standard guitar models without any need to tweak - but they are not - they are much brighter and full of high end - well the Tele Neck pickup model certainly is. So - I could go into Workbench and spend some time experimenting with the different volume pot values to see if I could match the tonal qualities of the model with the real thing, or I could experiment with the tone pot values and setting of the knob position to achieve a similar tonal quality. But these options seem way over the top and time consuming and unnecessary when the Variax models should have the input impedance modelled in some way already or at the very lest they should respond like the AUTO setting does for Guitar In and match chosen fx or amp, but they don't. They don't appear to have any modelled tonal attenuation due to "lead length" or "Input impedance" - they seem to be constant with no high end attenuation occurring as with a real guitar/pickup/lead combination. Does anyone know why the VDI implementation does not allow for any impedance matching like Guitar-In-z ? Does anyone have any suggested values for volume and/or tone pots that I could try in Workbench HD to make the JTV Tmod-5 model behave tonally like a real Fender Tele neck pick up in terms of attenuated high end?
