Finally I'm back home and I was able to play with the Baklengs! Of course did a side-by-side comparison with Bakfram.
First thanks you a lot Knut, for sharing here the info you had few more of these available for ILF after the first batch got sold out!
First impressions: I love both, but Baklengs does have few features I was hoping the Bakfram would have: first (like Fabrikat does) the possibility to have closed loop on the infinity switch (which now allows to use the pedal as a "proper" looper), as well as to be able to max the feedback on the fully ccw degenerative position, very cool indeed for instant self-destructive runaways!
In general, all the switches are the greatest update ever, as now you can easily switch direction, octave, and infinity modus!
Very first impression was both are very alike and can cover same grounds, but in depth experiments revealed few different nuances.
Mod: Bakfram modulation is more lofi, and adds a lot more crackle and noise, while on Baklengs beside introducing a bit of noise, Mod is more like you would expect from a tape wow/flutter, it's a much more mellow and vibrato style modulation.
Degenerative Feedback: Bakfram is more gentle, with the control maxed the degenerative side effect is "stubble" and won't go into self oscillation, while Baklengs can self-oscillate and be more aggressive, which I think is a great improvement, or expansion of this feature!
The delay/clock time seams to be tailored a bit differently: max clock and delay time seam to me to have the same length, while on the minum setting Bakfram gets more close to zero than Baklengs. This means that with Baklengs I can't recreate those super cool flanger/overdrive/filtering sounds Bakfram does (set like this: forward delay, no octaves, delay time at zero, fastest clock, feedback maxed out on the degenerative side, Mod how much you like).
Mix: Bakfram's Clock has some influence on the dry sound audio quality! Which is actually a cool shaping tool to filter also the clean dry sound (the slower CCW clock position, the darker the tone), while on Baklengs the Dry sound pass thru 1:1 as the original input sound, with no colouration happening.
Of course another main difference: Bakfram has the octave UP & DOWN, while Baklengs offers this super cool random back/forward option!
This said both pedals are amazing! Before trying both side by side, I was wondering to sell the Bakfram and keep only Baklengs, but... both are keepers!
As somebody else already pointed out here, each iteration this family has its own character. Plus you can get some wonderful texture when running one into the other.
Once again thank you Knut/Pladask: it's another great one you released!
