I spent days searching the internet for a solution to the volume drop I was experiencing using the Pod HD500X and the 4CM with my EVH combo or LBX. Turns out the solution was rather simple. All I am using the Pod for is effects in front of and in the loop of my EVH amps. I rely on my Evh blue channel for my guitar tone 😎
Once you have the pod connected to the amp using the 4CM, set your master volume to 12 o'clock. Then arrange the effects you want in front of the amp (make sure you disable the amp modelling) then after the mixer, insert an FX loop in one of the effects blocks. Sucks it takes up an effect position but what can you do. Then arrange the effects you want in the loop after the FX loop block. Simple as that. If you experience any volume loss plugging in via 4CM method compared to plugging in direct to the front of your amp, you can boost the signal accordingly in the FX loop block by increasing the db required on the return. For me I had to increase it 12db to get the same level of output. But it works flawlessly now, I get my EVH tone and all of the effects where I need them in the chain and no volume or output loss.
I have seen other posts talking about increasing levels in the mixer block, or adding an studio EQ to adjust levels....Maybe that was for something different? Not sure....But this is what worked for me and I am so glad I have the Pod and EVH paired and working seemlesly.
Happy tone chasing folks 😎 🤘 🎸
