Lately all I have been doing is running a booster into my 5 Watt Swart Atomic Jr. My favorites are: BJFE Red Rooster Booster (it makes everything sound bigger and you can control the tone by changing the Voltage from around 8 to 18. The RRB seems to work great into every amp I have tried it with), the Purple Humper and SBEQ are also very nice lower gain boosters! The PGC is a nice pedal booster and depending on the rig can work nicely as V1 blaster
I have a custom Arcane Analog Skullranger (this was purchased from the maker and the idea is very similar to the DAM RRB, but the Skullranger does not get ice picky when you turn the guitar down like the DAM. I love the looks as well!)
I also love the Swart Atomic Booster and Fuzzy Booster which are usually a bit thicker sounding than the AA Skullranger. If I do not use an attenuator I favor these two and the BJFE as they are a bit more refined sounding, but the Skullranger has a really agressive sound and that has its uses as well.
I have tried many other treble boosters I did not care for though I will skip the list unless someone is interested.
I tried the MP Ruby Red and it was always so thin and bright! Nothing like the BJFE RRB. THe Bearfoot SYODs can also work well as boosters if you run the Drive below 10:30. I have not tried a Baby Pink and since I had the buffer installed in my SBEQ I do not see a need.
Remember I tend to use smaller amps and Fender single coil style guitars, so a PRS into ? (Do you still have that Bludo?) might call for something I haven't tried. Still it is hard to go wrong with the RRB, SBEQ, PH or in a pinch the newer PGC.
