Hi Samuel, I can try to help you with a starting point. The Nashville 112 is a wonderful little amp with a big voice. I would start with the pre-gain on 3, Low on +6, Mid -4, Shift 800, High 3, Presence 3 and Post Gain on 4. No amp reverb if using the RV3. If you change the Pre and Post gains to a desirable volume keep the Post slightly higher than the Pre-Gain. Try it without amp reverb while using the RV3.
Try this on the RV3. Balance, barely open then after everything else is set you might adjust the Balance slightly to get the amount of effect you want. Set the Tone at 11:00 oclock the R Time at 1:00 oclock (as on the face of a clock). Mode on #7. I would go from guitar to the Lil Izzy, to the volume pedal to the input of the RV3 from the (mono) output A of the RV3 to the input of the Nashville 112. I hope this gets you close to what you want.
