First off, apologizes to Lyle for taking awhile to post this. I kept trying to get better quality clips to no avail. Which brings me to my next point. I don't carry around the tone describer handbook around like Rockinhorse1 and some others seem to do. So I attempted to get some clips to do my describing for me. I'm by no means a great player, I haven't even hit the 3 year mark yet. I'll post them at the end of my review. I NEVER play pedals. I don't own an overdrive and I have never found one that I like. To my they all have a chalky, ratty, unnatural sound and they never seem to react well dynamically. This thing was the total opposite. Smooooooooth smooth smooth overdrive. The pedal is really 4 in one. It is an overdrive, a clean boost, a dirty boost and a buffer. I'll go through each one by one. But first lets go over the construction. This thing is heavy duty. Strong, sturdy switches. The pedal itself feels like it would take a beating and as for more. No loose jacks, knobs or switches. My first impression of the pedal was how solid and sturdy it felt. Much stronger than anything you would try at guitar denter. I can't really tell you how it is as a buffer, I never used one before so I can't comment on it. But if it is anything like the rest of the pedal the quality is top notch. On to the boost(s). The pedal offers a very clean and transparent boost to hit your preamp with. Very transparent, reacts like an amp when I rolled down my volumes. at times I would forget I even had it on. The pedal has a "soft drive" mode which is like a dirty boost. On the side of the pedal there is a button to toggle between the two. There is a control for how dirty you want it to be. I loved to use this with my amp set slightly dirty and it would kick it to another level. Very useful. On to the overdrive. There are three voicing buttons on the top side of the pedal. A low cut, high cut, and a voice. I personally only kept the voice button one way. (I can't remember if it was in or out at the moment.) The voice switch seems to kick in a lot of mids, which I preferred. The lo cut was useful for high volumes in the mix to cut through better. And I always kept the hi cut on to keep everything smooth. The are knobs to control the tone, the output and the amount of gain. I never put it past 1 O'clock because I don't play high gain but it could really get up there. Nevertheless, no matter how much gain it would clean up with your guitar volume. Something I consider the best feature of this pedal. No loss in dynamics what so ever. Especially which me not being a pedal guy. I would set it on and control everything with my guitar volumes rather than clicking it on/off. The highs are buttery smooth, and it sounds nothing like your typical overdrive. It reacts like an amp and sounds like an amp. I love that. Lastly you can drive the OD with the boost. When both are on it automatically is in softdrive mode. Lots of gain, no fizzyness, I didn't use it much since I'm not a big gain guy but it is very very usable. I think pedal guys would like it alot for songs that have a clean part, a dirty part and a lead. Pedal off for clean, Maybe a boosted clean for a clean lead, OD on for dirty rhythm and both on for leads. Overall what impressed me most about the Telos was its ability to NOT sound like a pedal. It sounded like an extension of my amp, and reacted dynamically like my amp. Onto the clips. They were all done at a local blues jam. I played out of a SF vibroverb using my P90 LP/SG hybrid. As I stated before. Not being a pedal guy I just clicked the OD on and left it on the whole set using my volume knobs for cleans/leads etc. I used a cheap digital recorder so pardon the quality. I stayed on for around 8 songs, the bassist that come on for 3 of them didn't know where he was at all so I cut those and another one, the mic overloaded. And once more, bear with me, I am experienced, not a good player and, being a blues jam, all of it was improvised. This first clips is an instrumental, the bassist just started with a lick and we all followed him. I started with an awful slide lead so please pardon me on that one. Highlight of the song is my rhythm playing during the bass lead. The OD was on I just used my knobs to get a nice clean sound. Jam September 14th - Folder Shared from Box.net - Free Online File Storage Here we did whipping post, wasn't used to playing it in G so I had a few slip ups. And in the intro I dropped out because I'm used to the singer I usually play it with coming in much earlier. I take the last lead and I play the leads in the chorus. Jam September 14th - Folder Shared from Box.net - Free Online File Storage Thrill is gone, once again, clean sound but the overdrive was on. The other player is playing a very thin sounding strat so its easy to tell who is who. I take the first lead, my volume knob only came up to around 7 (neck). Jam September 14th - Folder Shared from Box.net - Free Online File Storage This last one... alright if you have heard all of the clips and got the jist of it then ignore this. We had already played a few instrumentals because no singers showed up that night. So I sang for the first time live and I could've built a castle with the amount of bricks I shat. The only reason I have it on here is because it is a good demo of the pedal. My leads are prevalent since I kept forgetting words. So please, tune out my voice for the love of all that is holy. Jam September 14th - Folder Shared from Box.net - Free Online File Storage It's a kick ass pedal. In the hands of a real player it absolutely kills. I would like to give a big thank you to Lyle and Rich for giving me the opportunity to give the TELOS a try.
