Hey guys,

Lately I've been in the mood to tinker with my gear and I've always wondered what the difference was between a TS-9 and an 808. I've got a TS-9 that I don't use that much because I prefer my MXR M77 to it, due to its greater range of adjustment and the asymmetrical clipping.

***I use my ODs pretty much only to boost and tighten my 6505+ -- not for overdrive on their own. So considering that, will I notice much of a difference by modding my TS-9? What could I expect the difference to be? I'm confident that I can do the mod no problem, and it's cheap -- but if there isn't much of a difference when using it as a boost, why bother, right?

Short answer: No

Long answer: http://www.geofex.com/article_folders/tstech/tsxtech.htm


Pertinent Quote: "In terms of differences among the models: the TS808, the TS9, and the TS9 reissue are in fact built on the same circuit board pattern. For these three, THE ONLY DIFFERENCES ARE THE OPAMP TYPE AND THE TWO OUTPUT RESISTORS. This is how the various conversions to "TS808 specs" are done - two resistors are changed in value, and the opamp maybe changed to another type."

No, you will not notice a difference in sound between the 2 at all.

There are a ton of great, easy, worthwhile mods to the TS-9. The 808 conversion isn't one of them but I know Keeley had his mod schematics available online for a while, and I'm sure there are dozens of other quality mods readily available with a bit of searching.

the keeley mod is nice and helps retain some lows the TS normally cuts out

So a Boss SD-1 then...

No the TS type pedals still have a mid/hump that the SD1 doesn't have (without tweaking)

I have a number of Ibanez Tube Screamers. I have a TS10 that was modded to TS 808 specs many years ago by Robert Keeley. The difference between my normal TS9, my original TS10 and the modded TS10 is almost insignificant. It's mainly a tonal difference and even then it's not a very significant difference. The TS10 is normally a little brighter than my TS9 and both are a little brighter than the modded 808. Nothing a little extra bit of EQ can't change if needed. If you want to mod something buy a TS7 on EBay for $35-40.00 and mod that to 808 standard. (People should be snatching the TS7 while they are still inexpensive. Just 5 years ago you could get a TS10 for $30-40.00 now they go for $125.00 and up. The TS7 is still a bargain. Get them while you can.)

If it's just a boost thing you are looking for I don't think you'll notice any difference.
Yes I am guitarded also, nice to meet you.

The Bad Monkey is a great pedal. Very much like a good Tube Screamer.

I'll throw in a green rhino or SD 805 which are basically TS type pedals with controls over all 3 frequencies (to different extents).
Charvel So-Cal (SH6TB/N, killswitch), Jackson RR5FR (TB6/Jazz, Drop C). Joyo pxl pro.
Loop1=Crybaby from hell, Boss PS-5, Seymour Duncan 805 or Green Rhino, EQD Hoof or Earthbound Audio Super Collider. Loop 1 into ISP Decimator II.
Loop 2 (FX loop)-Line6 M9, TC Spark Mini. Loop 2 into mxr 10band. All into a Peavey Triple XXX 212, Ibanez IL15.

I don't really want any new OD pedals. My MXR is awesome out of the box. I was more or less just interested in modding my TS-9 to maybe get more use out of it. Sounds like the 808 mod won't make any difference for my application. It's funny how they charge so much money for the 808 version, when really it's hardly any different. Might be interesting to do that Keeley mod myself though; so it doesn't cut quite as much bass.

the sd1 still has a pretty big mid hump, at least to my ears and the way i use it. maybe not just as much, but i'd say it's in the same ballpark...

I'll have to put the Classic T models on my to-try list. Shame the finish options there are Anachronism Gold, Nuclear Waste and Aged Clown, because in principle the plaintop is right up my alley.

The main difference between the SD1 and the tubescreamer is that the SD1 has asymmetrical clipping which makes it sound a little bit raspier imo.

yeah, sd-1 is mega-mids. doesn't sound great by itself, but is tits going into a lead channel.
#19
^ yeah. i also think it's maybe a little nicer/more versatile by itself than a tubescreamer... but then a lot would say that's not much of a recommendation either since a lot of people don't like a ts by itself either.

i dunno about that. the circuit topology is pretty similar, but a lot of the values are different. from what i hear from people who understand pedal circuits more than me, the asymmetrical/symmetrical thing doesn't actually make all that much difference. Or at least not as much as most people think, but it's the big thing that people with a rudimentary understanding of electronics (i.e. people like me ) latch onto since that's the bit that's easiest to understand.

I know the DS-1 has asymmetrical clipping, but I'm not sure about the SD-1

SD-1 is also asymmetrical clipping. In any case, I have an MXR M77 (Modified Custom Badass Overdrive, or something to that effect, lol). Anyway, it's based on the SD-1, only a lot less noisy, has a "100 hz" knob as well as a general tone knob, and a "bump" switch that shifts the pedal's EQ to emphasize a little more low-end and mids. It's a great pedal -- my TS-9 has felt left out ever since I bought it.

Yeah I was using a few TS type pedals for a while all the time. Now I rarely have them on, I go straight in pretty much

yeah i'm definitely guilty of that type of thinking too once you finally feel, "Oh wow, I think maybe I actually sort of understand that bit!" you tend to latch onto it. Or at least I do.

ds1 is symmetrical (to ground), sd1 is asymmetrical (in op amp's feedback loop), far as i'm aware.
