Until very recently I used a BOSS GT6 for effects. I rarely used the amp modeling. Anyway i decided to get some cheap stomp boxes to go with my Vox pathfinder 15 R as small portable rig i can throw in the car. After doing a bit of research i bought a Joyo Compressor, Joyo Ultimate Octave, Joyo Ultimate Drive and a Behringer Analogue delay (all up less then $200 AUD). Wow!! These are serioulsy good sounding pedals. for $39 the Behringer Analogue delay is outstanding. The Joyo Ultimate drive is sensational, very smooth and versatile - amazing value for the price (It doesn't need the Freakish Blues mod). I know there are better pedals out there, but for the price these are great. These pedals sound wonderful with the Vox, then I tried them with a couple of valve amps (Tweed Deluxe and Tweed Princeton clones) - Even better!!! I havent used the GT6 since.... NB Joyo Ultimate Octaave - great sonding Fuzz pedal, though I'm not as keen on the octave sound. From the interweb It appears that there is an error in the octave circuit, the fix is to reverse the polarity of two caps. I will try this eventually.
