I don’t feel complete traveling without a guitar. Fortunately my wife thinks it’s absolutely normal that I take my guitar with me, she even encourages me. My advice, don’t noodle scales if the wife is near, play something beautiful and relaxing using the looper, it might even make her fall asleep. That’s why I spent quite some time in finding a good travel guitar equipment.
If a standard electric guitar is too big, I take my Steinberger Synapse guitar, which fits in an extra-long suitcase. But most airlines accept a standard electric guitar in a bag as carry-on luggage.
Most practical solution is the Quad Cortex (which is surprisingly light), since it is very flexible with a very good internal looper. Kemper Player is also good, but it’s missing an internal looper and the looper pedal adds to the weight (I really don’t understand why Kemper would not include the Looper in a travel friendly device…???!!!???). If it has to be very light, the Tonex One is the best solution (you don’t even need a power supply, just use the phone charger). If you use it right, it sounds very good! And even together with the looper pedal it is still lighter than the Kemper Player, but it only has Reverb and Compressor as effects. Hotone Ampero Mini is not bad either, all effects and looper included, very light and small and the sound is more than ok.
For Speakers I choose between Marshall Kilburn 2 which sounds very good with zero latency (Attention! Many Bluetooth speakers have quite some latency on line in). Even better is IK Multimedia’s iLoud which gives you a great travel sound system even working fine for small spontaneous parties.
I would say that all theses solutions will sound better than any travel amplifier I ever tried, but that’s just my experience.
The best option in my opinion is Quad Cortex together with iLoud, sounds awesome and you can even connect up to 4 Instruments to QC if needed, each having it’s own signal path.
