03lewisjos Posted June 16, 2020 Posted June 16, 2020 Hi, I have owned a Diezel VH4-2 Pedal for some time now and I've been running it through the clean channel of my Boss Katana 100 MKI since I bought it. The pedal can be plugged into the effects loop of the amp so it can effectively act as a Diezel VH4 preamp but when I connect it this way to the Katana I get a very muddy sound that lacks bite and character, and I also get a lot of unwanted noise which doesn't seem to clear up too well with a noise gate. Just wondering if anyone else has had a similar issue or am I just being a noob? Any help would be great. Quote
Dad3353 Posted June 16, 2020 Posted June 16, 2020 I've no experience with either of these units (I'm very much more 'old school', and a drummer, to boot..!), but, in general, the Fx send/return would be used for 'end-of-line' Fx, such as delay, where the signal will no longer require extra treatment. I'd say that the best position in the chain of your Diesel pedal is between the guitar and the amp. That's how it was designed to be used; the signal level and impedance are matched to the anticipated input of a guitar amp, and may not suit the level and impedance of the 'send/return' jacks. I'm not at all sure exactly what sonic difference it would make to bypass the pre-amp stages of the Katana; I'm not enough of a guitar purist to offer any comment on that. Hope this helps, even if only slightly. Douglas Quote
03lewisjos Posted June 16, 2020 Author Posted June 16, 2020 Hi Douglas, Thanks for your reply. Yes you may be right about putting it between the guitar and the amp, but there is actually a designated 'To Power Amp' output located on the back of the pedal which is designed to be plugged into the 'Return' output on the amp. It's one of the unique features of the pedal which is supposed to in theory turn your amp into a Diezel VH4, it just isn't working well at all on my katana. Quote

Have you tried an email to Boss, or their Forums..? There is more likely someone aware of Katana issues there, I should think. It's a fairly specialised, recent, amp, so not much experience gathered in the Wider World, perhaps. Worth a try..? Quote
HateRedStephen Posted December 23, 2024 Posted December 23, 2024 Here's your issue: when you put the VH4 pedal in front of an amp (clean channel) then you have the sound coming from your pedal, wich is then colored by the preamp, and then sent to your power amp. in a serial effects loop, you are placing your pedal inbetween the clean preamp of the amp, and the power amp. so you are giving your pedal a boosted signal. why it is fine one one amp and not the other depends on your clean preamp settings. it's much better that you use the preamp out on the VH4 pedal, so guitar straight in the pedal and then connect the pedal with the preamp output (wich is the boosted output of the pedal) right into the FX return of your amp, so you are not using your amp's preamp. Glad to help Quote
