Mesa M-Pulse Big Block 750 Bass Head (2004) into Peavey 215 Enclosure (1986)

A very simple set up of a wildly unknown amp. NOTE: Sadly the main OD (all at 12 Noon including gain) tone file had an error I cant seem to fix. I will have to re-record it and upload at some point. So unfortunately you are stuck with gain at 3 and gain at 8 and no in-between. TIP: This sounds really good when you stack #01 (Clean) with one of the OD files by duplicating your track and running 2 instances of Gateway Plugin. Personally I like to boost the low end on the clean channel a bit and it absolutely rips. The Mesa M-Pulse Big Block 750w head with "SImul State" technology, running up to 8 stages of gain through 4 12AX7 preamp tubes and into their big block output transformers. This is the only bass amp I have ever come across with in-built overdrive, and it actually makes sense for bass and doesnt just suck out the tone. Like many Mesa high gain amps, the EQ controls on this are touchy and its hard to find a good tone... until you do. So I opted for a simpler "set it and forget it" type of setup, making variations of captures based on gain and channel rather than every possible change of the EQ. For all captures, both channel's master volumes were at 12 Noon (5) and with EQ as follows: Bass - 12 Noon (5) Passive Mid - 12 Noon (5) Active Mid - 9 o'clock (1 - very scooped) Active Mid Freq - 1 o'clock (7 - about 400-500hz) Treble - 12 Noon (5) The overdrive channel (CH2) is reactive based on the clean channel (CH1), meaning they share one EQ but also the clean gain affects the volume of the OD channel, independent of its OD Master. Minor adjustments to CH1 (Clean) gain were made when CH2 (OD) gain was reduced, in order to keep a similar overall volume. Microphones were phase-checked and summed, then run through the Distressor just to tame peaks and smooth it out a little. Distressor Settings: 2:1, Distortion 2 engaged, input hitting in the yellow consistently around -7/-8db with peaks crossing into red around -12/-14db reduction, slow attack fast release, output to match. recorded through Behringer UMC1820 and ADA8200 with Midas preamps, inputs hitting just below clipping, and coming into the DAW around -10db. Slight gain adjustment made in DAW to bring the peak level up to about -8db as recommended by Tone3000. Bass used to test tones was my 6 string LTD B206sm with stock pickups and their in-built active EQ preamp. Set with a slight bass and treble boost and slight mid cut, full volume, with pickup blender set to a slightly balance more toward the bridge to give it a full sound but with a nice djenty clank.
