Here is my current signal chain. Bass...tuner...Sansamp BDDI, (signal is split here)....one affected signal goes straight to a Morley ABY box then to MXR Micro Amp.....the other unaffected signal goes to an MXR M-80...Rocktron Moan/Wah...Chourus...Flange...Delay...then to the ABY/Micro Amp...then everything goes to my QSC. Reason for this of course is for the bass drop off from the wah. Everything would work beautifully except for when I want to combine the signals. If I play one or the other they are fine. However when I combine them...there is a compressed signal loss...low volume. I'm running the BDDI in the instrument level at this time...so it's essentially an effect right now, (not a pre amp). That's wht I have the MXR Micro amp for...a pre. All the tone shaping is done with the bass itself, M-80, and BDDI. Anyways...how do I get rid of this signal loss when I combine the two. If I could get the tubular valviness of the BDDI mixed with the ultra clean fat low of the MXR, and it's hyper distortion....Heaven.
