Its weird when we must talk or discuss the future but al i read is based on the past. I don't live in the future and try not to stay in the past to long I've never played with rack units only i have some rack gear in my homestudio for recording. My first guitar effect unit was on the floor in the 90's, it was the Boss GT-5, awesome unit with digital delays, mods, pitch, synth and even analogue drives, men i was so happy with it! I played for over 15 years with this unit to the point the love for pedals started and the GT-5 faded away. First a Voodoo Lab Sparkle Drive, second the Morley wah and now years later i have my own pedalboard which i control with the awesome Boss ES-8. Some digital pedals i control with midi, other pedals and my amp with control switching. I think pedals and pedalboards are on the top of their game at this moment but you already see more and more people downscaling. I did in some extend the same, the Boss ES-8 can handle 8 pedals so thats the max, not a pedal more All my modulation effects comes from the Strymon Mobius (cheating a bit), two overdrive pedals, a MIAB pedal, delay, compression, wah and a digitech whammy. Guitar players should restrict them self to a point you say to yourself, enough is enough. I sometimes see large pedalboards with dozens of drive and fuzz pedals. Buying new pedals and gear can be addictive but yes, in the end its a burden, the weight, all the cables and knobs, tone suck, you name it, and lets not forget the cost! I shall keep it short, for me no rack gear. If i start all over again i will probably buy a floor unit aka the AxeFX or the Helix but because my pedalboard is freakin awesome at the moment i think this will not gonna happen in lets say the next decade. I've worked hard for my gear and at this point i've got all the sounds and even more a guy like me can wish for that the future is not that relevant now. I live in the here and now and enjoy all the great stuff i have. Everything comes in waves so maybe the majority will lose interest in pedalboards and some will return to rack gear, who knows? I think digital is the future in amps, pedals and so on. I will be very excited to see what will bring us in lets say 2027. Till then, enjoy you gear and make great music.
