I'm bundling Tube FM 1-4 together. You get 15$ off if you buy all of them. That comes to a little over 17% discount. On top of that there is a bonus set. Some nuggets are in this set, I think 7 effects, and they each relate to one of the sets in the bundle. One is a pretty cool (stereo) reverb/delay that I used cassette tape to make, along with the really smooth Philco tube amplifier I got for Tube FM 4. There are even the two original prototype tube radio effects I made over a year ago, as an experiment, which resulted in all of the other stuff happening.
If you buy the individual sets separately, you still get the discount and bonus set. Just help me out by CONTACTING ME before buying the last set of the bunch. Toss me an email telling me what you have, and I'll send you an invoice for the last pieces of the set, then the links to what you need. This would be much preferred to you buying the last set, then me having to issue you a 15$ refund.
